There is no option to exclude recursive search and attribution of folder.jpg's as thumbnails

This is more of a feature request than a bug report :)

My Music Folder is structured like this: one folder for each artist, and inside each artist folder one folder for each album. Now, CT works pretty good, it detects the folder.jpg files in each Album folder and creates a thumbnail.

However it assigns a thumbnail also to the Artist folders, which by themselves are without any folder.jpg files. It does so by arbitrarily assign one thumbnail of the Album subfolders inside the Artist ones.

I dont want this. The Artist folders do not have any folder.jpg files for the specific reason that I prefer not to have any thumbnails for them.

I have looked for any option to deactivate recursive attribution of subfolders' jpgs to the main folders, but I didnt find any. Can the recursive search of images be disabled?
