I have been looking at a few photos of the A340 and I have noticed that the 3rd door(from the cockpit) is smaller than the rest of the doors, but on some they are all the same size. Why is that?

It's probably customer-specified. With L/R3 being larger, the aircraft is probably certified to seat more passengers. The smaller door would have weight savings on an aircraft that doesn't need the capasity. I'm not sure, but I think that's the reason.

that's exactly why 777236ER my airline has the larger 3LR doors because our 330 holds 340 pax our new 340 will only have 292 pax and the 3 LR doors are smaller.

I fly on both the 340 and 330, -200 and -300, and can attest that the size of the door 3 indeed dictates the max number of pax the aircraft is certified to transport.
In case of a small door 3, it is called an emergency exit and not a passenger door, and the aircraft is certified for 375 pax. With the large door the certification goes for 440 pax.
