Discsubtitle handling

[simoncn]

Thanks for clarifying that FRONT is the picture type 3 'Cover (front)' and DISC is the picture type 6 'Media'.

When MinimServer reads picture information from a FLAC or MP3 file, it looks for a picture as follows:
1) Use the first picture with type 'Cover (front)' if any such pictures are found
2) If no 'Cover (front)' pictures are found, use the first picture of any type

This means that when MinimServer scans a file tagged with both 'Cover (front)' and 'Media' images (in either order), it will use the 'Cover (front)' image and ignore the 'Media' image. I have confirmed that MinimServer is doing this with your test files. Does this work for your use case?

I also checked what happens with the M4A file. This has an unusual format with two blocks of tags. The first tag block is read by MinimServer and contains a single image of type 'Cover (front)'. The second tag block is not recognised by MinimServer and contains two images of type 'Cover (front)' and 'Media'. I will need to do further investigation into what this second tag block is and whether MinimServer should be reading it.
