To display em using img tags, the link needs to end in ".jpg" (or .bmp, .gif etc I expect). For some reason that gallery won't display a direct link to the photos - probably to stop people linking to it & sucking up bandwidth...
Unless you can find the direct link to the picture, you'll need to re-host them somewhere else - there are plenty of free places out there.
edit - unless the site's also got a way of linking to pics hosted in that manner! lol
