im new to photoshop...i just got it today and i got tha 7.0 version...iwant to learn how to make my picture look just like tha scarface cover and how to make my picture look cartoonish...and different cool images...can some one help me

First of all: to be certain about whaqt I say, you better wait till some1 with lots of posts reply as well to be sure he doesn't say I'm wrong, But I think I'll be rather correct :D
I can tell you that photoshop is a rather complicated program: you can't just give the command "make a cartoon from this", but you have to do almost everything yourself (ofcourse you have LOTS of tools avaible). When you talk about the scarface cover I assume you mean this:

To get a similar effect I would try this:
-)Image-->adjustments--> desaturate
-)Image--> adjustments-->Brightness/contrast
Increase both lightness and contrast and watch the result

I don't think I would be able to make a good cartoon from a photo, but I think it should work using some filters...
