I'm not sure this is possible but can perl be used to read gif and jpg image headers and retrieve width and height in pixles of the image?  The problem is I don't even know where this info is in the image headers let alone knowing how one could get it using perl.

Thanks

Then, do:


use Image::Size;

my($x, $y) = imgsize("something.gif");

One of the problems with autograding (allowing things to just get a 'C'), is that it sometimes becomes difficult to get your questions answered.
