It can't find the texture map for an object you placed in the project.
Which object calls the image?
Is it a tree? A pine tree, perhaps?
ArchiBAM? They use textures for leaves.
Furthermore, Pine1 is not in your library. Use your system tools to locate it and move it to the library.
You probably got this object in an archive file and the missing image wasn't included in the archive.... so it might not be there at all.
Or I'm wrong.
