I have found that I needed to set EVERY file to 777 CHMOD So It could be changeable...
But now I think there's an error on Util.php itself, I go updating and then when it comes to:
http://britneypictures.org/util.php?numpics=15&startpic=4670&albumid=0&autorefresh=1&action=update_thumbs&updatetype=0
I mean when the startpic goes to 4670 it doesn't work anymore, It stops, the page even loads...
What It's wrong?

try setting numpics to a lower number... maybe even 1

Some files stills doesn't want to get updated
Maybe because they're too much large?

Usually they don't update if they're non image files or if the systems resources aren't sufficient (as you already said)
