I would suggest opening up photoshop and using the help index, its probably quite simple, unfortuantely i have it on none of my PC's - so i can't give you an A-B-C on how to do it.
as with all things - its a learning curve, but certainly on a graphics level on a MAC, photoshop is pretty much as good as you get as a general graphics program. Alot of people use photoshop - so i would suggest getting into it a little for its graphical capabilites. If you get to the point of mastering it and want to get into motion based animations - then illustrator, which is also made by Adobe, is a worthwhile move.
happy site building - hope to see you around the forums.
