Is it possible to configure the time that it takes to rotate between images?
This has come up before so it may be worth searching the wish list board for a request that you could +1
That indeed looks like the default Large Album theatre mode, but the mention of rotating images totally rules that assumption out.
When it comes to TMs, the rotation of images is a feature exclusive to artist pictures only (not album artwork), and there's already a setting for it if the above is indeed a custom TM.
A search for
rotationInterval should bring up more info.
When you double click the artwork, you can see it in real-size. This is fantastic, but would be great to be able to change to the next one when desired
Double clicking the artwork opens a temporary copy of the image in your default image viewer - this app will have no knowledge of any other images in the music files or folders.
By the way, getting the album cover to open to an external image viewer is not an option that is on by default, I believe (users have to enable it from Preferences > Tools).
But yes, even with MusicBee's native image viewer, one cannot browser through the next/previous album covers.
There's a fairly recent request of this that I just can't find right now.
EDIT: See point 4 here
I already spend hours on end on social media. Might as well spare a few of those to a greater purpose here.
