What happens if you don't know the aircraft's registration?

Hello JP mods and fellow photographers.

What should I do if I want to submit a photo but don't know the registration? I took this shot earlier in Sydney (under the flightpath of runway 25) but didn't catch the reg of the plane:

Can I still submit the shot if I don't know the aircraft's registration?

If you have absolutely no clue, then you can leave the reg field empty, if you get the rest of the info correct.

But I think that you might be able to make out the reg under the left wing in the full size original.

Thanks Stefan, I did try looking at the original shot off the camera but the angle didn't allow me to make out the registration.
