Embedded artwork problem

[pgbj]

Hi

I decided to add REPLAY_GAIN (ALBUM) to my library - something to do in lockdown really. So I used dbPoweramp to batch encode the RG and add the ID tag. I checked the results in mp3tag and all looks fine - including the album art.

However, for every album that I have processed minimserver 2 no longer seems able to serve the album art - neither in album view or track view. (In my case I have art embedded in the audio files using mp3tag plus I have a folder.jpg in each folder). Bubbleupnp shows the cached thumbnails but gives 'Error downloading from server" if I click to see the art and shows nothing where its not cached.

I tried another client and same result - no art on the processed folders. Yet in mp3tag everything looks fine.

I have restarted and rescanned; I have rebooted the NAS.

Any thoughts?
thanks
