Hi Darren,
It's ok to upload more than one shot as long as it's not the same view. One nose-shot, one side-view, one rear, etc. it's ok. But, for ex. four pics of the left side, gets a little cumbersome for the screeners. Thanks for asking.

Michael,

Please define what you mean by frames, if you are talking about same aircraft type but different airframes/registrations then yes that is fine.

Currently we have no bad double rule like other sites, however, that may change if people keep uploading seven or eight shots of the same aircraft (as in same registration) from the same day/location.

And yes, this is happening in some cases although they are very few and far between at the moment and that is the very reason other sites have a bad double rule.

I hope that clears it up

Oh, I forgot to say, in the Air-to-Air category the limit is 11. ::thumb_grin}
