As you can appreciate photos this size are rather large and not every site minds you uploading them
So both of these photos are currently up on
GigaPan They also have the viewers for such big images.
Taken with the K5 with a Pentax*A 645 300mm, wasn't the best day due to smoke haze etc, but I'm happy with the end results.
The first shot is a heavily cropped and scaled down so I can get it on flick, the original is 990MP, this cropped version is 250MP which is enough make out some of the offices.

The 2nd is 2.15 Gigapixels, but no smaller version.
