Hey Stamp_Guy!
I searched the CPAN with the two words in your question title (okay, minus the last 's'), and surprise! here's Image::Size.

(allright, I also admit that I have this module installed for a while on my box too :)

The format recognized by this module are:

• GIF
• JPG
• XBM
• XPM
• PPM family (PPM/PGM/PBM)
• PNG
• TIF
• BMP

If you plan to use other formats, Image::Magick handles tons of other format, but is also more expensive on resource.
