Hello, It seems to be true that it because restricted memory size. I am having the same problem too with all of you. I am currently doing GIF decompressor. Only Small gif image can be loaded and it sometimes got some distortion. For bigger dimension, it always comes with 'fatal exception' or 'word non alignment'. Is there anyone who can help how to fix it properly?
