ImageEngine will enhance your responsive images by enabling support for HTTP/2, automatic webp conversion, Client Hints and more. It is likely that ImageEngine will shave off 50-60% of data traffic generated by images on your site. To better support mobile devices, ImageEngine relies on WURFL for server side device detection in cases where responsive images and client hints fall short. WP ImageEngine is compatible with the changed `` tag introduced in Wordpress 4.4, while still providing full support for older versions. The plugin will prefix your image `src` (URI) with your personal hostname which refer to the image optimization servers. In addition, Client Hints will be enabled by adding a meta tag in your markup. The plugin will automatically optimize the images you include in your posts and pages. For images baked into your theme, there is a php API available (See FAQ). Registration is required to get the most out of ImageEngine. There is both a completely free option, and a commercial option. == Installation == 1. Upload `plugin-name.php` to the `/wp-content/plugins/` directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3. Go to settings page and save your preferences == Frequently Asked Questions == = Do I need to register to use ImageEngine? = Yes, you can sign up for a free account [here](https://scientiamobile.com/imageengine/signup#imageengine-lite) = Do the plugin support all themes? = Your theme has to support html5 (most themes does today). If you install the plugin and can't get responsive images to work properly, try adding `add_theme_support('html5');` to your `functions.php` file. = Is the plugin compatible with other plugins? = If you have other plugins altering the URLs of images or plugins for other CDNs you might want to do a test before launching. We constantly monitor this, but if you stumble upon a case of incompability, please submit a ticket. = Can I use it in my theme or plugin ? = Yes. Use this function: `` * `$url_to_convert` is the full url, including http(s)://, to the image. * `$options` is an array of configuration options. If not set, values from plugin admin page will be used. The array looks like this `array("key"=>"xyz","key_type"=>"normal","w"=>0,"h"=>0,"pc"=>0,"fit"=>"")` = What are the differences between ImageEngine and ImageEngine Lite = ImageEngineLite is our community offering of our ImageEngine service. Our premium offering of ImageEngine provides more parameters and no bandwidth limitations. = Is ImageEngine a CDN? = Yes, for all practical purposes it is. ImageEngine runs on several locations, including Amazon. However, ImageEngine can also play together with your existing CDN if you want to keep it. Either in front of- or behind your existing CDN = Does ImageEngine make changes to my images? = Yes. In order to optimize the image we need to make changes in size, croping, aspect ratio and compression. You accept that we can do this by using ImageEngine. However, you still own your images, including the derivates, during their lifetime in cache = Can I see how much data ImageEngine is saving? = Yes, by logging into your account. = What are “Client Hints”? = Client Hints is an emerging standard, spear-headed by Google, which enables the browser to append information about how an image should be displayed, such as size and device pixel ratio. ImageEngine uses this information if it is available. With the addition of WURFL data, ImageEngine has all information needed to produce an optimal result based on how and where a specific image is displayed. = Which PHP version? = PHP >= 5 == Screenshots == 1. This is the lite version and all possible settings. In this example plugin functionality is deactivated. 2. This is the pro version and all possible settings . In this example plugin-functionality is activated. == Changelog == = 1.0 = First version. = 1.0.1 = Text changes and admin notification.
