I'm looking for a good php image upload package in php

[Armethius]

I am having the hardest time finding a solution that is:

1. PHP
2. Cross Browser (At least IE, Firefox, Safari)
3. Offers image resizing

I've taken a stab at writing my own function, but I can't get it to work with files uploaded from macs (i'm suspecting it is the "meta" stuff that apple wraps around its files.)

Does anyone have any suggestions here? Open source (GPL, MIT, BSD) is preferable, but i'll consider anything at this point.

Thanks!
