Scripting problem

[Tobias Diedrich <ranma@example.com>]

Hi all,

How can I figure out the size of an jpeg image ?
file returns me the size of pngs:

|ranma@example.com:~/mantrha/bilder$ file animelyrics.png
|animelyrics.png: PNG image data, 88 x 31, 8-bit colormap, interlaced

but not of jpegs:

|ranma@example.com:~/mantrha/bilder$ file mononoke_hime.jpg
|mononoke_hime.jpg: JPEG image data, JFIF standard

Is there some tool which can be used in a script to figure
out the size of an jpeg ? (would be even better if it does other
formats too)
