I finished uploading all scans a while back and here they are:

I put a summary on the page linked to above.
I had fun with Krystal Hosting's support team in regard to the site's thumbnailing of large images; around 4000 pixels on any edge.
I contacted the developer of the SLIR script and it turns out to be a memory limitation in PHP.
I can see the script complaining of memory exhaustion in the PHP logs.
The people at Krystal kept reporting (3 times): "we've increased the memory, check it now".
The last time, they said "we've upped it to 1GB; the maximum for this hosting plan".
I can see in the PHP logs, the amount of RAM available was 1GB even before I reported the issue to them.
Useless as a sack of dead gerbils.
So, I implemented a 'workaround' on the site. For the huge images, I upload the original file plus a downsized-but-still-big image that SLIR can process.
The original is a hidden file called ".filename.ext".
When the website indexes the non-hidden file, it checks for a hidden, larger equivalent with the above naming convention and, if it finds one, it displays a "hi res" link to the larger, hidden file as well as the visible one.
Dream big and bold and daring.
