This plugin is very important for many of the sites that we build. However, unfortunately, the resized animated GIFs sometimes lose their colour vibrancy and look much more dull and faded compared to the source GIF. See an example of this here:
One idea for this plugin would be to bundle it up with ImageMagick, or check for the presence of ImageMagick on the server, and if it's there, then use this to resize the image instead (which would work better than deconstructing the image in PHP).
convert big-animated-gif.gif -coalesce temporary.gif convert -size <original size> temporary.gif -resize 100x100 small-animated-gif.gif
Or perhaps using the Imagick PHP library:
I uploaded a GIF that displays normally in a web browser but when uploaded using this plugin the animation added a big blue box to the GIF. This plugin would be helpful if it were usable.
The library used to manipulate the gif files is not very efficient : using it with a big gif file (1920px X 1080px) made my computer (local server) crashing. I tested other library with the same file without issues.
I have also tested with a smaller gif file (http://www.creativereview.co.uk/images/uploads/2012/06/tumblr_m46uw7z5x61qzw1qyo1_500_0.gif) and the result was not correct : a green artifact appeared in the resized versions.
