Hou to add CBR and CBZ to auto contenttype: images

I'd like to have folders that contain CBR files to have the auto-content-type IMAGES.
But I can't get it to work.

I've changed the filetype CBR to the group IMAGES but nothing changes.
I've added a MIME/type: image/jpeg to it. Nothing changes.

It DOES work when I view JPG-files but not for CBR.
When i manually chage the contenttype dropdown from NONE to IMAGES i have a very nice thumbnail-view. Now all i want for it is to do it automagically :slight_smile:

What did i do wrong?

Does it work if you:

[ul][li]Create a new folder[/li]
[li]Copy, say, 20 CBR files into it (and no other files)[/li]
[li]Navigate to the parent folder[/li]
[li]Close the window[/li]
[li]Open a new window, and navigate to the folder[/li][/ul]

?

Your test did not come up with something new - even after closing and killing DOPUS/DOPUSRT.

It DOES work on my laptop... so I'm going to reinstall my PC anyway and check it again later.
Thanks Leo.
