Hi,
I think that slight modification of media update daemon would easily add this feature. I also have a lot of files with "windows" like additional info (screenshot has same name, but .jpg at the end).
I vote for such feature - it's trully desired in my case... Till then it would be also convenient if editind coverarts from web-admin would allow to add screenshots for all files in same directory (currently you have to add one by one)....
Regards,
Rob.
