=== Twitter Image Host === Donate link: http://atastypixel.com/blog/wordpress/plugins/twitter-image-host Tags: images,twitter,hosting Requires at least: 2.6 Tested up to: 2.9 Stable tag: 0.5.2 Host Twitter images from your blog and keep your traffic, rather than using a service like Twitpic and losing your viewers. == Description == Keep your traffic in the family! Host Twitter images on your own site, with support for comments and trackbacks, image resizing and thumbnailing with Lightbox. Twitter doesn’t yet come with its own inline image support, so we tend to be limited to using image hosting services, and linking to them with short URLs. So, services like Twitpic host the image, and we direct traffic to them in return. Better to take advantage of that traffic, and host images on your own site. This way, viewers come to your site, instead of someone else's! Posted images are displayed in your normal Wordpress template, with support for comments and trackbacks, without any setup required. Most themes should work with this, but if not, or if a different layout is required, a custom theme template can also be provided (see 'Creating a Template'). Provides an HTML form for posting image content, as well as an API modelled on that of [img.ly](http://img.ly/pages/API), compatible with Tweetie (for iPhone) and any other Twitter clients that speak this protocol and offer configuration of custom image hosting services. Uses Twitter's authentication and a list of authorised accounts, so you can let others use your image host too. You can even post status updates to Twitter while submitting images. Provides a widget and shortcode to display uploaded images. This supports filtering by Twitter account, styling with CSS, and Lightbox/Thickbox. Mac users, grab the Automator service from the [plugin's homepage](http://atastypixel.com/blog/wordpress/plugins/twitter-image-host) to be able to upload via a context menu item in the Finder! == Installation == 1. Unzip the package, and upload `twitter-image-host` to the `/wp-content/plugins/` directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3. Visit the settings page and add your Twitter account to the list of authorised accounts 4. Start submitting images - See the 'Posting Images' section for more If you find Twitter Image Host useful, please consider buying some awesome [Mac/iPhone software](http://atastypixel.com/products). Then tell all your friends. == On Comments and Trackbacks == This plugin uses a series of filters to make submitted entries mimic ordinary posts, so that they can be commented upon, and trackbacks left. This system is not yet perfected, so while commenting and trackbacks are supported, some quirks exist. For example, comments and trackbacks that are left are not visible in the comment manager in WP's administration. This situation may change as the plugin matures, but for now, please be aware of the limitation. == Frequently Asked Questions == = I get "Couldn't place uploaded file" messages = You probably need to create the folder in which Twitter Image Host stores uploaded images -- it will try to create the folder automatically, but it will fail if it doesn't have permission. Create a folder called `twitter-image-host-content` within the `wp-content` folder of your Wordpress installation, and make sure it has write permission for the web server user. = I keep getting 404 errors = Make sure your blog is using URL rewriting (i.e. your permalink structure is anything but the boring default `?p=###`). == Widget == To use the widget, simply visit the Widgets page and drag the "Twitter Images" widget into a sidebar and configure it. == Shortcode == Shortcodes are snippets of text that can be inserted into pages and posts. These snippets are replaced by various generated content. Twitter Image Host provides a 'twitter-images' shortcode to display images you have uploaded within a page/post. Available parameters: count Number of items to display id Single ID (eg 'abcde') of one image to display, or multiple IDs separated by commas (abcde,fghij) view Image thumbnail view: squares, proportional, large or custom custom_thumbnail_width Custom width for thumbnails, when 'view' is 'custom' custom_thumbnail_height Custom width for thumbnails, when 'view' is 'custom' custom_thumbnail_crop Whether to crop custom thumbnails author Comma-separated list of Twitter account names to limit results to columns Number of columns of images to display lightbox 'true' to use Lightbox/Thickbox Example: [twitter-images columns=4 lightbox="true"] == PHP function == As well as the shortcode, you can also use call `twitter_image_host_images()` from within a template to produce the same output. Pass the same arguments as the shortcode as associative array values:

Recently submitted images

'ATastyPixel', 'columns' => 6, 'lightbox' => true)); ?> Tip: Use this in the `twitter-image-host.php` template (see 'Creating a Single Template', below) to display other posted images when viewing an image. Use `the_twitter_image_author()` to filter the list, to show only other submissions by the same Twitter account as the one of the currently displayed image. == Template Tags == This plugin provides several template tags, for use both in displaying single posts (see 'Creating a Single Template'), and for custom pages which display many posts in a loop (see 'Using Template Tags in a Loop'). The available template tags are: = Single Entry Tags = *`the_twitter_image_permalink`* Returns the URL to the view page *`the_twitter_image_url`* Returns the full URL to the image, or the image thumbnail if the original image was large *`the_twitter_full_image_url`* Returns the URL to the full-sized image, if one exists, or false otherwise *`the_twitter_image_title`* The title of the image *`the_twitter_image_date`* The date (timestamp) of the image - use date() to configure the display *`the_twitter_image_author`* The associated Twitter account *`the_twitter_image`* Returns HTML to display the image and a link to the full-sized image if it exists, with Lightbox rel tags. = Loop Tags = *`query_twitter_images`* Search for Twitter images Available parameters (passed as associative array): count Number of items to display id Single ID (eg 'abcde') of one image to display, or multiple IDs separated by commas (abcde,fghij) author Comma-separated list of Twitter account names to limit results to *`has_twitter_images`* Use with loop: Determine if there are more images *`next_twitter_image`* Use with loop: Get the next image = Creating a Single Template = By default, this plugin will use the standard post template ('single.php'). However, if you wish, you can create a custom template to display hosted images. The template should be called 'twitter-image-host.php', located within your current theme directory. Creating a template to use this information is fairly straightforward if you have just a little knowledge of HTML or PHP: 1. On your server (via an FTP program, etc.), navigate to your current theme. This will live within `wp-content/themes`. 2. Copy an existing template - `single.php` is usually a good candidate - and call it `twitter-image-host.php`. 3. Open up `twitter_image_host.php`, and delete everything that looks post-related: This usually includes everything between the `have_posts` call and the matching `endif`, and may include some other surrounding content like an 'Edit this post' link. 4. Replace that which you have just deleted with something that uses the 'single entry' template tags above, like the following:

From on

5. Save the file, add some content (see the 'Posting Images' section), and see how it looks. = Using Template Tags in a Loop = Just like the WordPress Loop template tags, the template tags provided by this plugin can be used to display multiple posted entries. This can be used to create a custom page template that lists all submitted entries, with more flexibility than that offered by the shortcode. Use begins with a call to `query_twitter_images()`, possibly with an argument to configure the search. If the result is true, then the loop begins, conditional upon `has_twitter_images()`, and starting with `next_twitter_image()` to load the next entry. The single template tags can then be used to customise the display of each entry. Here is an example of use:

There are no Twitter images.

== Posting Images == To start posting straight away, a simple form is provided at http://your-blog-url/twitter-image-host. Enter a title for your image, your Twitter account details, and select your image. Hit Submit, and you will be given the URL for the image. To access this facility from an application, use the access point http://your-blog-url/twitter-image-host. The API is more-or-less the same as that of [TweetPic](http://twitpic.com/api.do), [img.ly](http://img.ly/pages/API), etc. To post from Tweetie 2 for iPhone, visit Tweetie's settings, and within *Services, Image Service*, select 'Custom', then enter `http://your-blog.com/twitter-image-host/upload` For Mac users, an Automator service has been created to upload images by right-clicking on a file in Finder, then selecting a context menu item. This service can be downloaded from the [plugin's homepage](http://atastypixel.com/blog/wordpress/plugins/twitter-image-host). == Making the URL even shorter == If you run Wordpress from a sub-directory (for example, http://your-site.com/blog), then the short URLs generated by this plugin will look like `http://your-site/blog/xxxxx`. You can remove that 'blog' component via a little `.htaccess` trickery. Here's how: 1. Create and open a new file in your site's webroot called ".htaccess". If there's one already there, just open that up and prepare to edit at the bottom. 2. Add the following, replacing 'blog' with the real subdirectory under which Wordpress is installed: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/([^/]+)/?$ RewriteCond %{DOCUMENT_ROOT}/blog/wp-content/twitter-image-host-content/%1.jpg -f [OR] RewriteCond %{DOCUMENT_ROOT}/blog/wp-content/twitter-image-host-content/%1.png -f [OR] RewriteCond %{DOCUMENT_ROOT}/blog/wp-content/twitter-image-host-content/%1.jpeg -f RewriteRule (.*) /blog/$1 [L] This will take any requests that: * Are located in the web-root (start with a slash, followed by anything but a slash until the end) * Have a corresponding file within Twitter Image Host's content directory Then, it'll rewrite the request silently to the real Twitter Image Host URL, without the viewer seeing. 3. In Twitter Image Host settings, set the 'Override URL Prefix' option to 'http://your-site.com/' == Changelog == = 0.5.2 = * Fallback to index.php template if 'single' template can't be found = 0.5.1 = * Added character counter to HTML submission form * Bugfix for when content folder doesn't exist = 0.5 = * Implemented a widget, shortcode and standalone PHP function to display uploaded images (see documentation) * Implemented loop-style template tags to create custom pages for displaying entries = 0.4.4 = * Fix to HTML submission form for WP installations within a sub-directory * If a tweet is too long, report by how many characters = 0.4.3 = * Minor tweak to suppress missing argument warnings = 0.4.2 = * Improved Twitter error reporting * Fixed bug causing incorrect API response = 0.4.1 = * Bugfix in URL creation = 0.4 = * Improved support for running out of a sub-directory = 0.3 = * Fixed bug that interferes with some other plugins = 0.2 = * Proper support for trackbacks, comment feeds, fixed a bug which caused plugin to say Twitter was unavailable when the Twitter account has no direct messages = 0.1 = * Initial release == Upgrade Notice == = 0.5 = This is a major release that introduces a widget and shortcode to display entries = 0.4.4 = This update fixes the HTML image submission form for WP installations within a sub-directory = 0.4.3 = If you are getting 'missing argument' warnings, install this update. = 0.4.2 = This update fixes a bug that stopped Tweetie 2 for iPhone working with this plugin.
