I have already asked in another forum, what about the line breaks in the description?
Currently no \n are converted to ```

What helps?

found

Question: Does this conflict with newly saved descriptions?

OK, i have test it.
Zenphoto don't save line breaks as ```

But, for what is this?

This don't work with line breaks.

`outputs the album description as saved. Zenphoto generally does no output processing. For formatting use plain HTML, for example by using the default plugin TinyMCE4. If you don't want to use that, you need to format the output just like you do vianl2br` or whatever else on the theme side.

What's the difference between
getAlbumDesc()
and
printAlbumDesc()
except "echo"?

OK, i have found it in the docs.
