Have a look at this.

I believe it is a PCI slot. There are graphics cards avaliable for that slot but they won't be anywhere near as fast as AGP or PCI-e.

What is you location? I know where some PCI cards are avaliable in the UK.

if this is same model as yours its pci-e. the picture you posted tell me you need a new camera too.lol, kind of blurry ,the small brown slot above the pci slot has something to with it ,its only pci-e 1 though it think

from the link below .
# Expansion Slots Total (Free) 1.0 ( 1.0 ) x PCI - DIMM 240-pin , 1.0 ( 0.0 ) x Memory - LGA775 Socket , 2.0 ( 1.0 ) x Processor , 2.0 ( 1.0 ) x PCI Express x1
