Extension:ImageCompare

This extension adds the  tag which displays an interactive slider for comparing two images side by side.

Usage
To add two images to compare, use the  tag with these attributes (bold ones are required):


 * img1: The title of the image to the left ("before").
 * img2: The title of the image to the right ("after").


 * width: A number specifying the width for compared images in pixels. By default, images are added with their highest resolution.
 * mobilewidth: A number specifying the width of the images for the mobile version, also in pixels. If not specified, it will be 320 or the specified width if it is smaller.

The titles must not have the File: namespace.

The inner content of the tag will be ignored.

Ideally, the two images should have the same width and height.


 * Examples :
