I'm uploading my photograph scans to flickr.
There's some nice USN stuff there, like a complete photographic survey of the Albany class CGs, and Post WW2 fleet boat conversions.
My Flickr
It automatically resizes my scans down to several levels of detail; yet retains the original file size -- which saves me an enormous amount of time in managing them online for people who want them.
To download the original:
1.) Click on Photograph.
2.) Click on the Magnifying Glass with a + in it (located between the NEWER and OLDER image buttons)
3.) Click on View all sizes button
4.) Click on Original.
Save the huge ass PNG you get.
