you have to read the image file as binary and decode it to know the size. python xbox has no library to manage/handle images.

about transparency you can define the alpha channel with xbmcgui when you display an image.

i can get the width/height using some libs of pil. that works very well but i didn't manage to get the gifs transparent. it looks like the hex colorkey doesn't work. i tried with different gifs. i used exit.gif and that image was transparent but it didn't matter when i changed the colorkey; it stayed transparent. but that is a 32bit pic. i have to handle 8bit gif images.
