Photoshop is the name of a program. You need to draw the avatar yourself (either on your computer, on paper than scan it in, or take a picture with a digital camera), then upload it to the internet. If you don't have access to those things (I don't) you can usually get a free trial of an art program that expires after so many days, which should give you more than enough time. As for uploading it, you need somewhere to store the files. I use a geocities account to store files, and there are other free sites where you can do it as well. Does that help?
