Why can't I click on this link with a nested image in IE7?

Open the following page in IE7 and try clicking on the image within the category boxes:

As far as I can tell, I'm not doing anything outside of the scope of (X)HTML/CSS, why am I not able to click these?

The problem was the display: block on the span surrounding the img. Removed that and tweaked the styles to make it look the same and all is good now.

This seems to be a known phenomenon:

• IE Image Link Fix

• IE7-/Win: Not clickable image in a link (caused by hasLayout)

giving the img a float: left as well might help, and should cause no change in layout.
