Thumbnails in subcategory missing pictures

[BamBanana]

Hi.

I'm trying to get my shop running but I have a problem – my subcategory thumbnails are not showing on the category page. Please see attached photo.

There is apparently a malfunction in Black Office that causes the uploaded images to not land in the correct folder to visualize the pictures – see link: http://www.frokenanna.dk/13-toj

I have tried to upload the various thumbnails directly to the ftp-server in the folder ... /img/c/, which they should be in – and of course, with the name "id_medium_default.jpg", but it does not help. Can you see which folder they should otherwise be placed on the ftp-server, or if I do something completely wrong?

I don't want a topbanner on subcategory, only the thumbnails.

Version: 1.6.1.15

Can anyone help me, please? I spend 4 hours trying to figure it out and i can't. 

Thanks to everybody in advance for your answer!

I don't think images are uploaded from the admin because img tag is missing on the category page which means images are not uploaded from the backend.

Oh... But how do I fix it?
