So, do you have any plans on adding wiretap support to detect GIF and
JPEG? You could use Ethereal to open a GIF or JPEG file, wiretap detects
it,  a new protocol "File" is used, instead of "Frame", to show
filesystem fields (size, mtime, atime, ctime, filename), and then the
appropriate dissector is called.
