Form / Image field not resizing

Applications Forms
#1

Greetings,

We are having a problem with a form that has an image field which is stored in the database. On the field, I specified Image Height of 75 and Image Width of 75, and Open in Another Window = Yes.
This works fine in the development project but when we deploy it, it does not work. it just displays the full image size and will not open in Another Window.
Production server is Ubuntu 12.04 32 Bit with Apache2 and PHP 5.3.10.
We have poured over the php.ini and other items and cannot find a reason it will not work in production.
Any ideas?

We did not have the GD libraries installed on the production server.
