if scanning my artwork, I discover that when extension was written in capitals, the art was not recognised
also if the name of artwork exist a capital, it will not be recognised

examples
Thumb.jpg give no result
thumb.JPG give no result

thumb.jpg give a result

I had in total 564 albums with JPG in the extension and change them manually into jpg and all the covers where back

formaly I use vista and ther the problem does nor exist

Hope I have you informed well, if not, contact for more "better"explanation

Thanks
