I'm sure the code could be optimized a bit more. It's looking at every image tag on the page, which might be slow depending on how many images you have.
(/.png$/i) part is using regular expressions (regex, for short): http://en.wikipedia.org/wiki/Regular_expression The $-sign indicates to look for ".png" the end of a string. The "i" indicates that it's case-insensitive (therefore .png or .PNG will match) I'm only a novice with regex, but it's quite an art in itself once you see what it can do.
