I was having the same problem, in my case it was testing out fine on a mac in Firefox and Safari but broken on a PC in internet explorer - as a temporary fix I bit the bullet and put a table in my template css file... here's my original post: http://rsgallery2.net/component/option,com_smf/Itemid,17/topic,6420.0

That said, I did a quick check to see if removing the div tag worked on my staging site (with out the table addition) and it seems like it did!?!?! Though since I don't have a PC I decided to leave the table in on production site for now. Here are samples if you have a minute and can take a look to see if both are working I'd on a PC I'd be your best friend 

Production Site (WITH table and removed </div> tag): http://iheartracing.com/index.php?option=com_rsgallery2&Itemid=67&page=inline&id=1&catid=1&limitstart=0
Stage Site (NO table just </div> tag removed): http://krazekimmy.com/index.php?option=com_rsgallery2&page=inline&id=2&catid=1&limitstart=1
