[NSFW] Footer Banners Problem – Please help me

I have uploaded a few banners to the footer of my website. The problem is I still need to upload a lot more and every banner I do is going to appear
below the one before. Basically its 1 banner in 1 row where as sometimes I could even put 3. It already looks stupid as its going down quite a lot, I have tried <span></span> also tried a few other tricks but nothing seems to work. Could anyone help me out with this? Would be much appreciated.

The banner are here londonescortfantasy.com
