I would appreciate some suggestions for stitching together scanned
sections of large format diagrams (schematics); photo editors such
as Photoshop or the GIMP require a lot of resources, are often
sluggish (if you don't have very fast hardware) and require a lot
of tedious manipulation to achieve the result. There are photographic
panorama stitching tools but these too may have problems with a large
number of high-resolution scan sections on slower hardware. Microsoft
Photo Editor 3.0 had features that made the task quite simple, but
it is difficult to install as a stand-alone app without a version
of Office.
What are folks using for a simple solution to this task (other than
purchasing an expensive large-format scanner)?
I use several programs. Photostitch 3.1 came with my Canon Camera.
Not the best, but good enough for my panorama photos. Example:

Find someone with a Canon digital camera and borrow the CD.

I use some specialized panorama software for taking radio coverage
photos from the top of towers and rooftops. My favorite of the week
is Panorama Factory:
<http://www.panoramafactory.com> ($80).
Note that to do any panorama properly, you need an indexed sequencer
with a built in 2 axis bubble level. Something like:

I have no idea what you mean by "large" number of "high-resolution"
images. Some numbers would be nice.
I've stitched together about 30 images, consisting of 8 megapixel 24
bit BMP images using Panorama Factory without difficulties. The
result was something like a 1.5 Gigabyte file size. It also took
about an hour on my ancient PIII/1GHz. The latest version supports 64
bit processors, which may work better if your images are truely huge
and numerous or possibly hitting a 2GByte file size limit.
