I don't know why but I have one machine that when I do a ⌘-Shift-4 the screen shot is saved as a png instead of a jpg. Does anyone know how to change this?
I'm not sure and a quick check didn't reveal an answer, but I do know you can convert images within Preview; just save as and choose another format. Sorta a long way around, but...
I've used SnapZ Pro for years. It lets you choose the format each time you take a snap, but it costs a little.
Terminal Tips: Change your current screenshot format
by Cory Bohon on Sep 11th 2008
Do you like using the built-in Mac OS X screenshot utility but dislike the format of the output file? With this simple Terminal hack, you can easily change the file format of the image. Open Terminal.app (/Applications/Utilities) and type the following command:
defaults write com.apple.screencapture type jpg
You can replace "jpg" with your desired file format (example: tiff, pdf, png, etc.). If you wish to change it back to defaults, Mac OS X originally grabs screens in png format. To activate the changes, just logout of your account and then log back in.

Voila might be good and lets you do lots of marking up and organizing which is cool; there are others. Flysketch comes to mind.
