I've searched the forums and found that similar question have been asked before, but I did not find a resolution:

My predicament is this (hopefully I can save others from my pain). Windows Media Player has resized my glorious CD album artwork images... many of my images were 500X500 and WMP has seen fit to squish them down to 200X200 without asking me. This represents a loss of many hours of work.

I am willing to track down much of my altered artwork, but I am no longer confident using the typical convention of "folder.jpg" For this reason, I will work around Windows and set up my various applications to look for "Cover.jpg."
The first step in this process is renaming my existing folder.jpg files, as well as resetting the file attributes (Windows has also made many of the read-only and hidden).
I'm running Windows 7, and as described in the above URLs, many of my "folder.jpg" files do not appear. For example, I have selected one directory and though the search clearly shows 5 candidates for renaming, none of them appear in BRU.

Why are these files not available in the selection box?
Thanks!
