Animated GIF images are overused by many website designs and can be quite annoying.
This filter removes looping from animated GIF images. After showing all available frames, image animation will stop on the last frame.
In those rare cases when animation does show something useful, the user can simply refresh the page (e.g. by pressing Ctrl-F5 in Internet Explorer).
src_include and src_exclude parameters define a set of image URLs to which filtering is applied. Unlike the standard include and exclude parameters, which define addresses of the HTML pages containing images, these parameters define a set of URLs of images themselves (the src attribute of the img HTML element).
Format:
scr_include = url_template scr_exclude = url_template
Normally src_include list contains one “*” element, and src_exclude list contains exception URLs that you want to leave animated (possibly empty).
