v1.93d has an improved GIFtoIMA script.
http://www.easy2boot.com/configuring-e2b/animation/ has been updated.
GIFtoIMA.cmd now only uses frames up to frame #255 (maximum for grub4dos) and can also now save as JPG instead of as BMP to save space.
Note that using a transparent background setting for JPGs does not work well because some of the background pixels may be a slightly different RGB value, so if you want to use a transparent background for your animation, choose the BMP option (default).
I spent a LOT of time looking for a GIF editor, but eventually I found a utility
