Yep, just follow Jezza's link and press 'join now' in the top right corner, enter your email (i suppose you could use a throw away one if you wanted, but i used my own) make up a password, and enter your DOB and then you can upload any pictures you have on your laptop/ PC.
Click on 'choose file' and go to the picture you want to upload one by one (It doesn't suddenly upload all of the pictures you have on file or access your computer, it only uploads the pictures you want it too).
Then just use the URL as a link on AB as you would to a website normally. I am really impressed with it, have a go.
Unfortunately my garden looks a little shabby and leafless at the moment - that pic was from last summer - can't wait 'til spring! :-) xx
