Where to store a dynamically changing image ?

Hello All

I have a bit of a tricky one here.

I have created an add-on that creates a dynamicimage that my library parts UI loads.

So depending on the shape of the object, the image will change and reflect this shape.

It works really really well.

The problem is where to keep the image.

I can keep it in my library folder, but as soon as another user puts the folder in a write-protected position in their file system, it will not work.
I can keep the image in the ArchiCAD data folder, but I don’t want to have to load the ArchiCAD data folder as a library (ACAPI_LibraryPart_Register() only works if saved in an already loaded library).
I can keep it in the embedded library - but this will not work for teamwork and is not working anyway.
I can’t place it as an asset in my add-on - because they are read-only.
I don’t want to write it to the pln file as custom data - that would be stupid yeah?.

Any suggestions would be greatly appreciated. 🙏
