1) no one gave you any comments

2) hit the add reply button, then you'll see a bunch of buttons across the top of the reply box.
One of them looks like a demented pic of a mountain and a sun.
Click on it and then you'll see a bar with three options (add from url, create album and refresh). All profiles have a gallery named Gallery (rela imagination at work here)
If you want to just link a pic on another site, click on the add from url and paste the url in the box that pops up
Otherwise, click on your gallery and the choices will change to add from url, upload, refresh
Click on the upload, then browse to where you have the image stored on your pc (if you don't have it there, right click on the pic you want to save on a website and save to my pictures)
Select it, then click upload
Then scroll to the pic in your galler, click on it and it'll appear

I thought I'd already done a pics for dummines - wait, that was avatars for summies
