Positioning and overlaying image on another image

Question

See how the tiny Facebook icon is positioned in the lower right-hand corner over another image?

Answer 1

See my answer to this question.

The difference with your situation is that you don´t need any javascript if you don´t want to, you can just add divs to the html and position them absolutely on top of the photos.

I think I would personally add the divs using javascript anyway so that they don´t clutter the html.
