hahahah nice,,,,,, years ago when I became interested in photoshop, I had no knowledge about the graphics, but like you, I was good at MS paint, I learned only basics of photoshop from a tarining cd and then kept practicing...... and as you know practice makes man perfect. photoshop is a nice software and is easier than it looks.
so you are successfully enrolled........
First of all you have to get photoshop, I am currently using its CS2 version as my pc can not handle more highend versions of it, it totally depends upon u that which version u want to get becoz all version are almost same from 6.0 to CS2 (9.0), from cs3 there are minor changes in appearence.
so now tell me what u want to do I mean If you want my help in downloading it or so... by the way my suggestion is to get CS2 version.
waiting for your reply
