So I've had my macbook for a while now and now that I've gotten ahang of all the awesomeness that a mac holds....I would like to get some more programs/tools to use.

I've been kicking around the idea of getting photoshop CS (I have photoshop on my pc) but can't seem to find a good download for it on limewire.

I have heard of Gimp open-ware type photo editing software.

Anyway I am looking to use it to make website graphics with and stuff like that.

Anyone know of something I can use? Or have any other programs/downloads that are must have for macs?
