Just a quick guess, but you may find it's the classes.
If I'm correct, you have multiples of these "image pop-ups", all with the same classes.
so if you think about it, you have multiple little boxes with popup layers, all basically overlapping each other.
The problem occurs for the Popups though...
You have applied a z-index to the Links (a:info) when inactive and when hovered over.... but not applied a z-index to the actual tooltip/popup!
Try adding z-index: 30; to a.info:hover span
see what that gets you.
