There should be another option on the list of prioritized options for where to place Album Art images and the filenames. There are currently 7:http://www.rockbox.org/wiki/AlbumArt
My suggested addition would become the new option 2, pushing all others down.
The first option is currently the only option to allow for song-specific artwork to be displayed, but this requires naming the image files *exactly* like the corresponding sound file, which screws up directory sorting.
Therefore the option should be added that if no image file has an identical name to the sound file playing, it then looks for an image file which matches the current song's Title metadata, similarly to how the following option looks for a match to the Album metadata.
This could cause conflicts when two songs have the same name, or when a song shares the album's name, or the song name contains unusable characters, but such conflicts are rare and minimal, and if anyone cares all that much about such things there is already the built-in flexibility to get around such issues. The additional code required should be minimal (and already blueprinted within the other options), and have essentially zero impact on any other functionality.
I may try to write this patch myself (as i did with "shuffle + track skip"), but if anyone beats me to it, it would be appreciated
Edited to Add: I have created a working patch for this. It works as intended in the ipod 5.5 simulator. The code required is very small.
Could someone reopen FS#10905 so I can attach the patch there?http://www.rockbox.org/tracker/task/10905
Edited to add (x2): Someone reopened the patch on FS for me, and the patch is posted. If anyone can check it out and comment, please let me know!
