Viewed in firefox...this site is a mess!

I just opened this site in the Firefox web browser and it is a mess! The pictures are all out of place. When I came back from Russia my desktop computer had crashed. I had been posting this site in Linux Ubuntu. I loved it. I used the Firefox browser and sometimes the spacing was off, when viewed in Internet Explorer...but not as bad as it is now. I guess I have to go back to using Firefox and Windows XP. I don't like Windows XP but until I get a new motherboard and go back to Ubuntu; that's all I can do. I hope this works for you viewers. Sorry.
