Problems adding products on new server

[JStrider]

hey, we just moved our store to a new hosting plan and got everything setup

the host transfered everything, then I updated the ssl settings and then transfered over the most up to date database and shutdown the old server once the new one looked to be up and running without problems.

then today, a few days later we go to add products and its throwing errors when we click on preview when adding a new product.

the store is at www.talonarms.com
we are running zencart 1.2.5d

and these are the errors its giving.

Warning: rename(/home/talonarm/public_html/talonarms/images/products/P8060084 small.JPG,/home/talonarm/public_html/talonarms/images/original/products/P8060084 small.JPG) [function.rename]: Permission denied in /home/talonarm/public_html/talonarms/admin/includes/functions/extra_functions/functions_images.php on line 94

its definently something to do with including pictures. we are able to load products without pictures. I'm pretty sure I got gd installed properly... I'll have to look into it in more detail now.
