I don't loop throughall the frame's results, I use just the first frame, which is also the biggest. So, width and height will be correct...on the off chance that there's a comment on some other frame than the first, it will not catch that. I'm attaching an anigif so you can test the dimensions.
FWIW, take a look at how tracker-extract extracts metadata with libextractor - you might want to use a similiar format (eg Image.Height=10;\nImage.Width=10\n) for the format string. (GHashtable will overwrite values with the same key so it should be okay for animated gifs) -- Mr Jamie McCracken http://jamiemcc.livejournal.com/
