High-Resolution Image Downloads of 2004 Scan?

[nablator]

By batch processing, do you mean batch converting? Like converting all files to PNG / JPEG at once?

Yes, and it's very user-friendly, In the Tools/Batch Processing dialog you select the image files and the output directory and format then click the "Go" button. There is a "Transformations" tab for additional processing: all filtering/processing tools can be selected there and applied in sequence. For a better readability I like to correct levels, the scans look washed out without any processing.

   

I've been using XnView "Classic" for about 10 years, and found it very useful for basic everyday viewing and editing purpose (resizing, rectangle crop/delete/copy, levels, color and contrast fixing, etc.) and batch processing+conversion.
