Samsung SGH-T139

I have the SGH-T139 and have taken some pictures with it. There is no memory card slot, but I did obtain a data cable from an accessory store. My computer sees that something was plugged into the USB port, but doesn't know what.

What software can I use to help my computer gain access to the pictures on the phone? I really have no interest in paying any provider just to transfer pictures off the phone.

Thanks.
