For some Folder.jpg files the resolution of the image shown is low, even if the original folder.jpg is high quality (500x500), the cached image in thumbs folder is in low resolution. Both cached images are the same (low) resolution, files are exactly the same in size.

This only happens for some images. Samples are uploaded to the team internal thread.

h4. Steps to Reproduce
Create a folder in your Music share named "Chris Rea" and save the attached folder.jpg to it.

Browse your music in share view. First time you pass the new Chris Rea folder the display quality is good (since it uses the original file). Drill down to the folder & drill up again. Now the image is shown has low resolution. Check the thumbs/Music/Folders cache folder to see that both cached thumbs have the same resolution.

h4. Additional Information
Will attach zip file with folder structure to this bug.
