Methods of protecting images.
1. Watermark (light) ... can often be filtered/removed
2. Watermark/stamp (heavy) ... needs to be irritating to be effective
3. Rightclick blocking ... easily defeated
4. Dicing ... quite a useful technique, as it makes SAVE difficult
5. Overlay DIV, with a transparent GIF (catches out careless savers)
If you can see it, though, you can screengrab it!

For you incog....
1. watermarks can be removed, as described previously, using programs such as photoshop.
2. heavy watermarks will interfere with the image too much to be worth it.
3. rightclick blocking can be defeated quite easily so not too much point in doing it, someone who is determined will still get the images.
4. dicing, dividing the picture up into pieces and then hosting all of the pieces next to each other, so it appears as if it is 1 image, but if someone tries to save the image they will have to do it for each section, and then reassemble them again.
5. Overlaying is putting a transparent site on top of the image you want to protect; then if someone tries to highlight it or right click and save, it will save the transparent image instead.
hope that helps
