Now that I’ve got several gigabytes of photos that I’m trying to present every day, I figured it was time to go ahead and learn some batch conversion commands. Links from my search:

• ImageMagick
• Graphics from the command line
• More graphics from the command line
• Examples of ImageMagick Usage

mogrify looks the most promising so far. mogrify -format png -sample 100% *.jpg -comment "Copyright 2005 Brett Peters" may do the trick.
