That's very good TBH. It might be that fixing these two gifs is the best possible solution rathen then trying to do tricks with with datatypes. I need to analyze this further.
Correcting the two gifs solves the problem with the small and peculiar GifAnimas of AmiGG, but on the AROS Build, "standard" GIFAnim (the ones used on the WEB), they will not be recognized and cannot be executed.
With the Modified Descriptors, on the other hand, everything works perfectly, both AmiGG and "all" commonly used GIFAnimations on the Web, see screenshot.
To mean the Animations you see in the Screenshot with the AROS Build you cannot run them !
