Some links to better quality images. Probably my eyes, but I can't see a weapons bay? Possibly it will be fielded on the rumoured 2002 airframe?
Elsewhere on the net there is discussion of those photos... some have been analyzed for "tampering", and it seems that details like the edges of the control surfaces where they meet the wings, and sections of the fuselage, have been "smoothed" to eliminate detail... suggesting that those photos were deliberately altered to hide such things as the location/size/shape of weapons bays, etc.
