Where can I find one?


Try DS9, http://hea-www.harvard.edu/RD/ds9/ . It's a very capable little
viewer, with versions for just about any platform you might be using.

Yes, thanks. Another is a version of the NRAO one I found, whic was just a
clean non-install program.
This works http://fits.gsfc.nasa.gov/fits_viewer.html.
A difficulty with a lot of "utility" programs that are out there, is they
become hard to find after awhile. This seems particularly true of video and
still image programs.


Not installed? How does that work?


By that, I just mean that no complex installation is required. There are
no shared DLLs or libraries that need to be present, and nothing that
needs to be registered with the operating system. For the Windows
version, there is just the executable and a DLL that needs to be in the
same directory.

Yep, got it. Hard to believe such program still exist. ;-)

I'm not familiar with flash drive capabilities. How does one execute off of
a flash drive? What is special about such a drive in this case?


They're just portable USB disk simulators- you must know about these?

Somehow I read that as maybe a bootable device; otherwise, I'm quite
familiar with the device. However, I was "stormed" upon by two young guys
recently try to help me find a particular camcorder. They kept coming up
with stuff they wanted, but not what I wanted. They kept saying this one has
a really cool, great flash card. I was beginning to wonder if they had not
elevated the devices to a god-like status! Maybe even with a keyboard!

From a practical standpoint, just imagine a 1GB (or so) floppy. I only
mentioned them because the main reason somebody might want a web-based
viewer as you requested is so that it can be used on different machines,
where no local viewer is installed. But if you have DS9 on a USB flash
drive (on your keychain, perhaps), you can simply run the program from
any computer.
