You can do the same with a transparent PNG with text links on top.

But it still doesn't prevent screen shots or downloading of your image via Xtreme 5 / Web Designer:

File>>Import graphics from web >> http://www.darulweb.co.uk/designs.htm

Click image for larger version.  Name: importedfromweb.png  Views: 399  Size: 42.4 KB  ID: 62175


There are other image downloaders can rip graphics from URLs too.
