Pictures/Avatars

[Leilah]

OK. First, I am not sure if this has been asked already but here goes.

-What are the steps to post a picture?

-What are the steps in order to have an avatar that is larger than.. the avatars capacity?

(As in, how do i re-size it if i can't save the picture in the first place- i can only use the web-site's address.. & Does the picture not re-size automatically, or do you have to do it yourself until its the right size?)

Thanks!
