Byron "Hook" Hukee is a former USAF Skyraider pilot and the creator of the excellent skyraider.org. One of his pages is much like the warbird registry - an attempt to list each surviving AD/A-1 including at least one picture. I just helped him connect with TimAPNY in order to update photos of the TN Museum's A-1H.
I can't speak for Hook, but three types of photos appear to be needed: the airplane while still in service, different schemes it has worn, and how it looks today.
If you visit
http://skyraider.org/skyassn/skywarb.htm there is a listing so you can see what he has, plus a link to him for submissions. I'm sure he'd appreciate only submissions where you are able to provide permission for posting, ie. no copyright tangles.
I don't think he's looking to be overwhelmed with a sea of sumbissions, but if you can update what he already has, then we all win.
Don't forget to cc
http://www.warbirdregistry.org/ as there are photos missing there as well.
Thanks!
