I have been learning html and css and while I have found a decent book and a couple of great links that discuss the code part, I'm struggling quite a bit with the graphics portion. First, and foremost, now a days what is the target screen resolution and then say I wanted a header to span that entire section, how wide would it be? Also, I understand the programs like photoshop and gimp make bitmap files and illustrator makes vector images. What I don't get is often I see people taking images and then resizing them with code. Don't vector images scale better than the gifs and jpegs people are using? So should images be made to be the size that you want them displayed on the screen and then how do you plan for that? Any assistance or direction on creating graphics for the web would be greatly appreciated.
