...has written back to me, consenting to releasing the image on a requisite free license suitable for Commons. I will install it when he does change the license. --Mareklug talk 07:55, 8 July 2013 (UTC)Reply

Pending the license change. I've linked to an existing Wikimedia Commons photo of a Turbo Otter, which better represents the appearance of the incident aircraft than the stock radial engine version. I also sifted through the Keith B Pics photostream on Flickr.com until I found the specific link to the image, which offers all the available sizes. The biggest size is 500 x 357 pixels, most likely not the original camera image. The photographer's Flickr.com page is a mess, with no sets, galleries or albums, just one big heap of nearly 2,900 photos. — QuicksilverT @ 13:52, 8 July 2013 (UTC)Reply
Uploaded, placed. I asked Keith for a high-resolution image. --Mareklug talk 17:21, 8 July 2013 (UTC)Reply
The photographer just informed me via FlickrMail that he declines to provide a high resolution image under the free license, as he is still interested in selling that. He says the low resolution image should suffice for printing needs, and if anyone is interested in the high resolution image, to contact him (presumably via Flickr). --Mareklug talk 07:48, 9 July 2013 (UTC)Reply
