Hello.

i have this program which scans a directory for image files.
if i have more then 90 images the scanning takes sooooooooooo much time

especially when i need to check if the image is a reguler Gif image or Animated gif with the Movie() functions.

is there a fast way to scan imagesto receive resolution info + to know if a GIF is animated .... ?

After checking the gif file structure, I've seen that the number of frames aren't stored somewhere. It's just a stream of frames, so you have to parse all the file until you reach the end...
Not sure will be faster than the Movie() command.

There's no other solution AFAIK. It's like KameHameHaaa said,
the number of frames isn't stored inside the file.

Did you look at the file format descriptions for GIF89a on wotsit.org
or google?
