Hiya

You can post pics from your computer here on your profile. To do so go to your profile by clicking on your name anywhere on the site or the view your profile link at the top of the page next to the gears icon.
Then click on the photo album button, the last one on the right at the top of the page. First thing is to add your photo by clicking the browse button which will open up a new window for you to locate and add your photo. Then you will need to create a photo album by clicking the Create New album link, then type the name of your album and a caption (optional) if you wish. Click submit and your photo should be on. From now on when you add more photos just choose the photo album you want to add it to from the dropdown box and/or you can add more albums too if you like.
If you want to post a photo from the web, click the Post Photo button from your profile and add the link to the photo online.
Hope this helps and if you have any more questions please let us know.
Blessings to you all in
