I don't know about ImageMagick alone, but ImageMakick + Photoaddict will create a complete set of thumbnails with a HTML index gathering them all, helping you (or anyone else) to visualize the whole set easily.

check out the attached bash function which, in combination with ImageMagick 5.x will do the trick.

Thanks Nicolas and Martin. convert, part of ImageMagick, does the trick nicely. I thought the program was called ImageMagick, but I couldn't find any man pages about it - the capitals make it harder to find ;-) My script now converts the jpeg images on the fly if there's no thumbnail, so the users can just put any images in the gallery I was working on, and the thumbnails are automatially generated :-> Thanks again, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\

This script doesn't always work. If you just add a ! after the geometry specification it will, thusly: for image in *.jpg; do

convert $image -geometry 160x120! thumb-$image done

If you have ImageMagick installed (most systems do), try

for image in *.jpg; do convert -geometry 160x120 $image thumb-$image

To use this, put all your images in one directory and run the script. Change the thumbnail dimensions to whatever you want. Your thumbnail file names will all begin with thumb-, for example bike.jpg will have a matching thumbnail called thumb-bike.jpg
