You can't really. If the image is on your site somewhere and doesn't require
a password then other users can link to it. One possible way may be to place
them in a Flash animation instead, that way you could also place your
copyright information there and a link to your site instead in addition to
the picture. This can be time consuming though as any good picture you would
want to protect would have to be inserted into the flash animation. At least
this would force them to have to link to your flash file instead of the raw
image, and not all bloggers are savvy about inserting a flash file into a
web page as it's not as simple as inserting an image.
