Thanks, for detailed answer.
A couple of things I only meant for digital releases why don’t people upload the pdf booklet when they have one, I didn’t mean why don’t they construct a pdf from physical booklet, and I wasn’t suggesting as an alternative to front cover/back cover ecetera.
Not that easy, but maybe what I will have to do.
You asked the wrong person 
- I don’t tend to buy digital releases. I’m a CD man. Also the PDFs from a lot of those digital releases tend to specifically say “don’t upload” on them.
It is one of the things I don’t like about digital releases. No paperwork. No way to know who actually wrote the songs, etc.
Is there any reason why we can’t update pdf booklets? probably good to distinguish between home made ones and official release ones…
You can upload PDFs. It is an accepted data format. Just a lot less flexible.
Yes, I meant as well, not instead of…
It’s not instead. Both individual image files and a PDF can be uploaded to a single release.
yes, that is what I meant
Also out of interest, how does MinimServer handle/support pdf booklets?
Its a bit convoluted but they have added support that allows the pdf to be viewed if using Bubble uPnP control point, not sure if other control points have added support for using this feature.
