This plugin allows content owners to increase copyright security and add interactive caption, sharing buttons and Deep Zoom to their images.

== Description ==

This plugin lets you convert images on your page into a secure SmartFrame image and boost your pictures with:

* Image security - image encryption, advanced right-click and screenshot block, copyright notice appearing directly on the image on an attempt to copy or download it
* Smart compression - always load the image in the appropriate quality and size, based on the device
* Configurable buttons and image caption - add share buttons, full screen mode and interactive image caption
* Deep Zoom - allowing up to 400% zoom without a negative impact on your page speed


### Security and copyright protection ###

SmartFrame offers much more than a simple right-click block. Here's what happens when you publish an image on your website via SmartFrame:

1. The original image is uploaded and stored securely on SmartFrame Cloud. You keep the rights to the image and you can access, replace or remove it at any time.
1. An encrypted version of the image is then published on your website.
1. The image can be decrypted only by SmartFrame Viewer which is added to your website when you publish an image using the SmartFrame plugin.
1. Your image is then rendered directly onto HTML canvas in the end user browser.

This technology means that your images are protected not only from right-click and common screenshot attempts, but they cannot be found in the source code either. This will discourage most users from copying your images and it will also protect you from any malicious web crawlers which may try to scrap your content.


### Smart image compression ###

With SmartFrame plugin, you don't need to choose between high image quality and page speed anymore. Every time a page is loaded, SmartFrame renders your image in the highest needed resolution, based on the device used. It means that on a smartphone we will render the image in a much smaller size than for example on a 4K screen.

SmartFrame will never upscale your images, so make sure that the original images you upload to the SmartFrame Cloud are high enough quality to look great on large displays. The size of the original image will not affect the page loading speed but if the image is too small, it may not look good on large devices and it may limit the performance of the Deep Zoom feature.


### Mouse-over buttons and caption ###
#### Share Button ####

Sharing doesn't have to mean a risk for the security. If the Smartframe Share Button is enabled, it allows sharing your images on your conditions. It is never the original image that is being shared, but only a SmartFrame encrypted version of it. This means that your caption and any copyright information included in your SmartFrame are also passed along.

Pro Tip: SmartFrame collects data of where and when your images are being shared. You can access all these data in the Insights section of the SmartFrame Admin Panel.


#### Image Caption ####

Every time you add an image to your website via SmartFrame, you can add a caption to it. Depending on the Theme you select, it will always be visible on top of the image (Security Theme) or only on mouse-over (Presentation Theme).


#### Full Screen Button ####

If you enable the Full Screen button, your images will be available to see in the full screen, in the highest resolution based on the original image size and the device. Since the full screen image in high resolution is rendered only once someone clicks on the button, using this feature does not affect the page loading speed.


### Deep Zoom ###

SmartFrame Deep Zoom allows up to 400% zoom of your image, so your visitors can view the details of your images. Our technology renders the image anew with every zoom level, so the initial loading speed is not affected in any way.

Deep Zoom technology is also optimised for mobile where it is accessed through a pinch gesture instead of tapping. It works in the same way, with the image rendered in higher resolution with each pinch.


### SmartFrame Cloud ###

SmartFrame plugin uses fast and reliable image distribution cloud. It allows images to be encrypted and displayed quickly and securely in any geographical location. The cloud is a custom implementation of Amazon Web Services and features autoscaling, load balancing, frequent backup, 24/7 monitoring and 99.9% availability and is home to many large international businesses.

It requires a simple registration which is FREE for up to 2GB of images which can be upgraded to Pro or Enterprise plans for more demanding users. Registration also gives you access to SmartFrame control panel which offers lots of unique image tools. Read more about features [here](https://smartframe.io/features/).

== Frequently Asked Questions ==

= Is SmartFrame plugin really free? =

Yes, the plugin is completely free to use with the Free SmartFrame account which includes 2GB storage space for your images. However, if you want to increase that space and remove SmartFrame branding from your images, you'll need to upgrade to the SmartFrame Pro plan which costs €14 a month and offers 10GB storage space. [You can read more about SmartFrame pricing here](https://smartframe.io/pricing/).

= Which image formats does SmartFrame support? =

Currently, SmartFrame support JPEG images.

= What happens to the SmartFrame images when you deactivate or delete the plugin? =

If you deactivate or delete the plugin, your images are instantly converted to the original file format and remain visible on your website.

= Why do I need to create a SmartFrame account to use this plugin? =

We need you to create a SmartFrame account so you have access to the SmartFrame Cloud where your images will be stored. You will be able to use the plugin directly from WordPress, without having to use the main SmartFrame Admin Panel. However, if you'd like to have access to some additional features, such as custom Themes or tracking data, you should explore the Admin Panel.

= Where can I get the access code? =

If you already have a SmartFrame account and want to connect it with the WordPress plugin, you will be able to find the access key in the SmartFrame Admin Panel in My Account > Integrations. Simply paste this code on the plugin page and your SmartFrame account will be linked to your WordPress account.

If you don't have a SmartFrame account, you can start the registration directly from the SmartFrame plugin. You will be redirected to the SmartFrame registration page.

= What is the difference between SmartFrame and other content security plugins? =

Most content security plugins disable right-click and some keyboard shortcuts using JavaScript, leaving the original image file still visible in the source code. This will discourage most users from trying to download your content, but it's still fairly easy for a more tech-savvy person to get access to your original image.

SmartFrame adds a whole new layer of security to your images. Not only are the right-click and keyboard shortcuts blocked, but the image is also encrypted and cannot be found in the source code. This protects your images from most download attempts as well as web crawlers which may want to scrap your content.

= What is the difference between SmartFrame and other image compression plugins? =

SmartFrame doesn't change the size or quality of your original image - unlike most image compression solution, we optimize the image in its context, based on where it's displayed, and not before it's even published. We make sure that every time you publish an image using SmartFrame plugin, it is displayed on your page in the appropriate size and resolution, based on the device. That means that when displaying an image on a smartphone, we only load it in the small size needed for that device, and on a 4K screen we can show it in much higher resolution.

= Can I use SmartFrame only on some of my images? =

Yes. When using a SmartFrame plugin you can opt-in to use it for all images which you upload or decide whether you want to use it for a particular image every time you add an image to your post or article.

You can also decide which SmartFrame features are going to be available on a particular image by using SmartFrame themes. As a WordPress plugin user, you can select one of three existing themes, but if you decide to use [SmartFrame panel](https://smartframe.io/), you will be able to create your own custom Themes.

= Will SmartFrame have a negative impact on my SEO? =

No, SmartFrame does not have a negative impact on your SEO ranking. All the images converted to SmartFrames will remain visible to the search engine crawlers. You can adjust these settings in the Control section of the SmartFrame Admin Panel.

= Does the plugin work on all major browsers? =

SmartFrame images are fully compatible with Chrome, Safari, Firefox and Microsoft Edge browsers. [You can find more information here](https://smartframe.io/support/supported-browsers/).

= How can I remove "Powered by SmartFrame" label from my images? =

If you're using free SmartFrame account, you will see "Powered by SmartFrame" label in the bottom-right corner of your images. To remove it, you need to upgrade to the Pro plan, which start from €14 a month and additionally increases your storage limit to 10GB. You can upgrade your account directly from the plugin page inside of WordPress. [Read more about SmartFrame pricing plans](https://smartframe.io/pricing/).

= Why do I still see <img> tags in the text editor in WordPress? =

In the WordPress editor, SmartFrames are displayed with <img> as regular images, but they can be recognized as SmartFrames by the data-smartframe-enabled="yes" attribute. In the source code of the page, there will be no <img> tag however, and the SmartFrame will be rendered by the SF Viewer script.
