Image goodness for the Mac

Don't have photoshop? Try Seashore. It even supports layers.



And these are the alt-print screen versions for the Mac.

Cmd-Shift-3
Makes a copy of the entire screen

Cmd-Shift-4
Toggles a crosshair so that you can select a smaller section of the screen

Cmd-Shift-4-Spacebar
Toggles a camera for you to choose which window to copy. Selecting a partially hidden window will make a copy of it in its entirety. Sweet or sweet? :)
