do you mean just "inlining" an image or posting pics into the photo album?
doing the inline is easy, so long as the pic is already up on the web somewhere... just hit the -img- button and put the url of the image inbetween the -img- tags.
putting pics on the photo album isn't that hard, you'll need to first create your personal gallery (there should be a button on top of things in the album page), then create at least one album to start with (you can have many) then upload your images... it's pretty self explanatory once you get going.
The tricky part is knowing you need to create the gallery and album first. You should see a button called 'Create/Order Albums' where you can do this. click the little [?] button for help anywhere you see it.
Then once you have your pics in you can inline those as above... you can get the url of an image by right-clicking on it and selecting properties.
