The alt text shows fine. I see MAKE INDEX THUMB when I hover over the link. The title declarations have nothing to do with the alt text shown to you when looking at them. They are there to distinguish the links and make things work with ajax. You dont need a title aspect on make index thumb etc because that is a link to editphoto script it is not AJAX.
I hope that clarifies the confusion. You tell you you dont see MAKE INDEX THUMB when hovering over that link?
