Hi guys, I'm having some trouble editing the images in a bootanimation. When I opened them in GIMP, it wouldn't let me change the color balance/hue unless it was converted from Indexed to RGB. So I did so, then edited the files, converted them back to Indexed (because I figured they had to be) but when I boot it up, it shows the first image, then gets stuck there. I can open the files in GIMP and they show up fine. What format do the .png's have to be in? Indexed? If so, is there a specific setting that I need to use? Thanks!
