I am with Wolfgang on this. I really like a little more information than simply "Click Here".

Rather than the "Click" message, a brief description of the site could be used. Like:

Picture of Southern Copperhead

This gives folks an opportunity to decide as to whether they want to see a picture of a snake. But I agree also with others that it is a simple matter of a click to paste the URL:

http://gto.ncsa.uiuc.edu/pingleto/herps/images/snakes/contortrix1.jpg

I mean, it isn't any real trouble to accomplish and what harm can it do?
