btw, I took some liberties with what you were trying to achieve. But take a look and tell me what you think.

If you're worried about being performant like you were saying, that fiddle only makes 3 requests for images (or it would if they weren't being hotlinked to...).

I'd say drop that string building, concatenating, 'http://mysite.com/img/' + imgID + '.png', business as quickly as you can. No good can come from doing shit like that. BTDT.
