Clearly that function needs better documentation because from what I
can tell, you have misunderstood its purpose completely. The purpose
is to use tumme's "database" file and mark image files that have a
matching "tag" in the database file. What you *seem* to have tried was
to mark image files with a certain file extension, something that
dired handles very well itself. Did I interpret your intentions

Did you not stop and ask yourself why tumme would try to provide the
exact same thing dired does? ;-)

Great. If you try again it should be quicker, because the thumbnail
files are already created.

Yup. No such functionality added yet.

Correct. That's not implemented yet. Partly because I have dired in
another window, and I am using the "track movement" thing so that I
can see, in dired, which file point is on in the thumbnail buffer. It
would probably be quite easy to add that info to the thumbnail buffer,
but it would require a rewrite of the code that places the thumbnail
files there, and exactly how it should look must be investigated. It
is harder in Emacs to center texts under images and so on.

There aren't any.

Yes, I saw that too. I'll keep it in mind for future additions of

Thanks for testing!
