Publishing an “image gallery”

Imagemagick’s suite of tools includes montage which is quite flexible and useful for making a quick overview page of image.

• mogrify
• identify
• convert
• Sizing down a bunch of images

Warning: MOGRIFY MODIES THE IMAGES – ERASING THE ORIGINAL – make a copy of the images before you do this!!!
