An even nicer method is to post a thumbnail of the pic/screenshot which is a link to the fullsize pic, so:
This is the code I used for the above thumbnail. I like to keep my pictures on my own server and use igal to make the thumbnails. I can give you full details and a script to update them if anyone is interested.
Simply change the address of your server/folder/pic name in the code above.
This makes it easier for browsing pages with screenshots, as having a long page with massive images makes everything go slow.
