how to replace "slide show" with image?

I was wondering where to edit if I want to replace "slide show" link with an "image" link?

Also, for Album show, I would like to add something other then the "album title". For example, having a "slide show" link to the far end right of the title would be nice.

Currently for lightbox like view, you have to click a tinny bottom left corner link in order to show. Is there a way to change it by just clicking the whole thumbnail instead of the tinny square?

thanks
