Difference in performance between img tag elements vs divs with background images?

Question

Are there any differences in performance or load/caching behavior when displaying images in img tags vs divs with image backgrounds?

My example:

Answer 1

AFAIK, browsers cache images the same whether they're in a DIV or an IMG. In any case, I think this one of those cases where specific performance is defined as an implementation detail internal to each rendering engine (and possibly the browsers built around them). As such, it's both out of our control as designers/developers and subject to change from browser to browser and version to version. In other words, I wouldn't spend too much time worrying about it.
