Criss, you should maybe first make an export with copying images (be sure to use the "better collada exporter" instead of the standard collada exporter). This will make the proper structure. Then, if like me you use a different format for the files ( I have .dds in blender but I used .webp in godot), don't export the images anymore and instead copy the images you want in this new folder. And then change the filenames in the generated .dae file.For me, it definitely works.
