That’s really good :) you should find some tutorials to learn more. I think if someone has the imagination and the desire to do graphics, they can go far! I think it pays well, but how much? I dont know!
I wanted to do web design...but college got in the way, so not done much since, this is from 2001, when I was going though sites about graphics design!
thx, you first would design the site in PS, once you get it all how you want, you would use Image Ready to slice the images, from that you can use e.g. Dreamweaver to make up the design in HTML.
