And I guess that's why such pictures are so hard to come by. We prefer that scans be made at between 144 and 288dpi. The other way is to send it to us via Snail Mail. Not worth the risk of loosing them. That's the order the Tales were written.
Copyrights are a very complex thing.
A great many pictures on TenderTale come from the Naval and National Archives. Most of these are in the public domain - which means anyone can copy them for whatever purpose. On some of these we have spent many hours cleaning them up in Photoshop, and optimizing them for presentation on the Web. We can't grant permission for pictures we do not hold the copyright on. While the publication is technically copyrighted - the government doesn't enforce their copyright as long as proper credit is given.
