Album art indexing priority

[winxi]

Is there a specific reason that folder.* files have higher priority than cover.* files? If it isn't problematic, it may be worth considering to interchange these two in the list of priorities.
The reason is that when using the Windows Media Player with default settings, it downloads album art from the internet and stores it as 'Folder.jpg' in the album directory. These 'Folder.jpg' files are saved as hidden system files and are of quite low resolution, typically in the scale of a few kB. If one now manually stores high resolution album art as 'cover.jpg', MinimServer will unexpectedly provide the low resolution album art from the WMP. Not a big thing, but it took me some time to figure this out and since the WMP seems to be widely used, it is likely that some other user may experience this as well.
