They are not. You need to send John an email to get a personal login. His address is in one of these threads and also in the link you just posted.

Done, many thanks!

Hi:

I have begun a project to compress many of the files on my FTP server. This is possible because of a new software package that was designed specifically for image compression with little loss in quality. I have just completed Situation Maps , Lage Ost for 1941. The original images were between 50MB and 90 MB. The files are now between 2MB and 5MB. This will significantly reduce the amount of time needed to download the files. Just the Situation Maps section contains over 2,700 maps so the overall project will take some time.

Regards,

John

Hello John,

interesting project.
What software are you using for this task? My archive also shows some need for reduction.

Regards

Darius

Mass Image Compressor.

I have just started using the software so I can't recommend it until I have more experience with it. So far it looks good.

When I originally scanned the maps for 1941 I used an average quality scanner. The results where 'acceptable' at best. Scanning form 12942 and subsequent years was done with a high quality photo scanner. The results were much better. If the compressed versions of 1941 are not useful, I will put the originals back.
