Yahoo do I view full-size?

In Yahoo groups there is Yahoo photos. when you click on the thumbnail of a photo it opens it bigger, but not full-size. how do i get the full size picture!!! i remember reading something a while back about adding something to the end of the url but i cannot remmeber what it was…help me.


Yahoo plugged that hole a long time ago. As far as I know, you have to pay for yahoo membership to get the full sized images.
