It was me that mentioned that I liked that Emacs recognized that a
.thm file (in my case) was actually a JPEG file, and that I found that
conventient. I did not think about the security implications.

I would still find it convenient if there was a confirmation (as per
the different suggestions where the file extension does not seem to
match the file format).
