The image rescaling isn't a permanent thing, just 
sort of a "patch". I just put in the ability to 
decide whether or not you want to use the auto-
rescaler/splitter this morning and I'm still 
working on it.

I only get a few non-work days every once in a 
while to work on the site, so sometimes features 
are left half-complete but working well enough to 
be acceptable.

When complete, you'll have the option of turning 
on or off the auto-scaler (will always have some 
degree of artifacting) and password protection of 
large scans (will be the exact file you uploaded) 
on or off. IMO, the best of both worlds would be 
using the automatic splitter combined with the 
ability to open a full-size scan in a new window.

Screencaps beat everything outside of a large 
watermark, though. (We can also do that 
automatically.) Keep in mind it's hard to appease 
both people who want pixel-perfect scans and 
people who don't want their pixel-perfect scans 
to be used on someone else's website.
