[LDCad] Insert background picture to LDCad

[Johann Eisner]

I just added an image as a submodel using “Session,” “Add new...”, "data", in the hope that I could use the image as a reference for a new model as background.
Just like (here comes the bad S word) it is possible in Stud.io.
The image appears in a new submodel, but cannot be inserted into the main model or any other submodel.
No parts can be added to the submodel containing the image either.
Does anyone know what this function is for, or is it still in development?

It's for embedding textures into the mpd itself:

If you want to use the image elsewhere in the mpd you will need to create a (also embedded) part containing at least a single textured quad referring to it.

Native background images is something I have looked into multiple times but I couldn't make up my mind on how to implement it. 

So in short it's still a planned feature
