For some reason a gif I uploaded does not render on OGF. The file can be accessed perfectly well and the full picture can be used on my wiki page about the Agarderia-Karamsk War. However, if I make the picture any smaller, an error message pops up, as shown here. A slightly different error message appears for the actual image, which is here. I uploaded it again as 'Agarderia War', yet the same message appears.
Does anybody know what is wrong with the file and what can be done to solve it?
