Ambience setting: item for ability to change between dark and light ambience

could you resize your pictures smaller please? 1/2 or 1/3

Patch already exist ,: https://openrepos.net/content/eugenio/patch-select-color-scheme-ambiences

i'm not quite sure....
If the design and architecture is well done. then the call of the function is just a call on the same picture which is carefully stored on specific place for ambience (means it's duplicated and store in an ambience directory).
Make no sense to have the photo app picture as reference, because if the user change this picture, then ambience interface is no more consistent.

As didilalala told the patch exist, and works well for some people.
@Levone1 Maybe if you read all my threads again and especially the content of the links which are given.

The jolla team has already used a gui-element by creation process of the ambience.
The patch use a different one.
Then they could reused theirs (not from patch) by changing in settings...

I think I was clear on the issue. I just feel like it's less of an issue since 3.0.1. Light ambience has been improved, and it takes abot 7 seconds to 'create' an ambience using a picture, and choose dark or light, and about 4 seconds to switch ambiences from one to another, so might be less work all around to just edit your picture, and have alternate ambiences to switch, rather than trying to create a script or Settings option to do it on the fly, (it would probably take a few seconds to run). When the other threads were created was in 3.0.0, and it was more of an issue ...

Anyway, I have no problem with the concept, if someone wants to figure it out. I actually like to figure out jow stuff works in general...
