[AccessD] Print graphics file from Access

I'd guess that there would be some settings file for that app that tells it
what to save as and what the file name/ext. should be. These probably don't
coincide correctly. Feel free to forward one of the images to me if you'd
like me to help investigate.

Hi John:

It's purchased software which allows an ASP.Net website to capture
signatures.  The files are being saved as .jpgs.  Hmm, now I look at the
(sparse) documentation, there is no discussion of what file format is being
output.  Maybe I made an assumption I shouldn't have.

I've never had any problems opening the files as .jpg in any graphics
program - maybe the file extension is being ignored.  Which would lead to
another question - how do you tell the file type without an extension?  I
can't find anything on Google.
