(before asking this question I checked the issues but none solved my problem)

I created a custom formatter:
thumb => to an image formatter
full view => to a path to file formatter

When I click on the thumb it just goes to the exact location of the image (=path) instead of showing a pop-up with the full view formatter.

I have downloaden the highslide-min and did put it in the highslide/highslide-directory.

Now what I expect is this: I set the file path to sites/default/files/highslide
But I don't see any images created in that map.

Any idea what could be the problem?

Thanks in Advance!
