I didn't believe this before, and I don't believe it now.
There is no rational reason to assume that an extension of .jpg
means the file can't do harm.  Most users do NOT feel suspicious
of files on account of a name ending in .jpg.

If indeed it is safe to open images if and only if their extensions
say they are images, the reason would have to be something more subtle
than what people have said here so far.

You can for example have heard that a new security bug was discovered in jpeg libraries. Then you would avoid opening jpeg images until this has been fixed.

In such a case it is important to know how your program will open the images. (Will the program use the jpeg libraries?)
