You can save the picture from rubberslug using 
Netscape, the rightclick disable only works in IE.
I don't think there is a way to stop people from 
getting the image, except to not post it, because 
they can get it from the cache also, so I 
wouldn't worry about it.
 
As for the seller keeping the cel scan  on their 
site maybe , they just forgot to update that 
section, and if it bothers you , you should email 
them personally.
