Profile...I'm thinking you are talking about your Avatar (picture underneath your username):
Go to "User CP" (upper left) and then click on "Edit Avatar" (on the left)...then you can either upload an image from your computer or insert a URL from a website.
Gallery: Click on the gallery, then go to whichever category you want to put your pictures in (Member, Main). Then on the far right, click upload photo....then just fill in the appropriate spaces.
Let me know if you need any help
