Have you been Fuskered? It is a site that will grab your art (images) and display them with out links to your advertising. All you get is the tag on the image if you put one there.
They can grab your whole gallery (or file of art) and place the images in a slide show for their surfers all on your bandwidth. Again without reference to or link to your sponsor or you if you're the sponsor.
This is in obvious violation to license agreements with many sponsors on use of their art. You've got the gest or it. Not the first site to come along with this.
Whether you can really call this theft is open for debate. Google links to images, but......
A simple demand email removed my links from their site:
