Short description of error
When you open a library from the addon and then load a texture, it uses a relative path to the initial scene and not the one we intend to modify.

The relative addressing of textures does not seem to work well, because the addon seems to use the path of the "parent" file that contains the linked object and not the object we are modifying.
