Well most are pretty much the validator being too strict.

There is two errors one is
vb in your html where they define the html statement you could change that to something like this
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" dir="ltr" lang="en">
You also have an invalid tbody statement somewhere in
vb. I do not beleive we use tbody html anywhere in photopost so thats an error in your
vb header footer somewhere.
The only real error is you could alter the copyright statement in our mysql settings table of Photopost and replace the & with & but thats it.
