Those are my shock mounts Simon?

For just the picture, the

are there just to tell the computer that it is to show the picture found at the address inbetween. To find out what that address is, right click on the picture you want and then go to "Properties" where it will tell you the address. Note that this isn't necessarily the address at the top of your screen in the browser.
For the hyperlinked version, the first address is the full sized pic, and the second is the thumbnail address as it will appear in your post.
