Sometimes that doesn't work. In that case, right click on the photo, and you should get a menu with four options. Click on "view selection source."
That will give you a bunch of gobbledygook like this:
<div class="ic-w300 ic-cntr"><div class="ic-w300 ic-m" id="vv4-44_idiv"><center><span></span><img style="width: 213px; height: 159px;" src="

In this bunch of stuff you will find:

Copy and paste this on your browser, and you will get an image that you can right click and save.
