Hello,
Just wanted to report a little bug I've stumbled upon: In foobar2000 1.5.1, if the cover art of a file is smaller than 35 KB it doesn't get displayed in the Album Art viewer and the default folder.jpg is displayed instead. This happens on both MP3 and FLACs (probably on other codecs too, but haven't been able to test them)
Steps to reproduce:
1. Create a folder.jpg image
2. Add a different image with a file size smaller than 35 KB as front cover art to a file
3. Display the file in the Album Art Viewer
Result: Album Art viewer displays the folder.jpg instead of the cover art.
It isn't something game breaking, just mildly annoying. But I still hope you can fix this bug soon!
Never mind, just noticed that under Preferences > Advanced > Album art > Embedded vs external the option "Prefer lager" was enabled. By setting it to "Prefer embedded", the problem was solved.
