If you are editting your message wall greeting, clcik on "edit greeding" and, on the right side of the page there's something called "add features and media". Inside it are "gallery", "photo", "slideshow", etc.. Just click on one of those things to do what you want to do.

For editting your profile, it's pretty much the same, you just now have to click "insert" at the top to get the same things.
