1. website? if so, how much real estate in pixel dimensions do you have to work with, how many pages? What do you images/screenshots do you need to establish this project in context?
I’m going to put the illustration in msnbc.com in health section. I will do some screenshots from the actual website

2. print? if so, what magazine, newspaper? What dimensions do you have to work with?
I will create the illustration either in illustrator or flash. Both of them are vector graphic programs so I don’t really need to think about the size first. But probably, it will be around 450 x 550 pixel if I do it in flash and do the roll over image mapping.
