Here's a link to the fb pic.

You can't link directly to your fb page because only your friends can see the pictures. If you want to use a link from your fb page you need to right click the picture, choose "view image" and it will open on a page of it's own. You can copy paste that link here and people will see it.

I suggest not using links though because people don't like to click the links. You will get more responses if you insert the picture directly into the post. I use photobucket, it's free and easy. Once you upload your pictures you will see links under the picture. Copy paste the "IMG Code" into the post and there you go!
