**Blender Version**
Broken: (example: 2.73 RC)
**Short description of error**
Image.copy() does not repair relative filepaths if they are "based" on a file in another directory.
**Exact steps for others to reproduce the error**
In {F135963} , 'a/a.blend' references the Image 'logo.png' relatively (i.e., with path '//../logo.png'). File 'b.blend' references the Image object 'logo.png' from file 'a/a.blend'.
To reproduce:
- Open file 'b.blend'.
- Execute the statement "D.images['logo.png'].copy().filepath" in a python console.
The resulting filepath should be relative to the file 'b.blend', i.e. it should be '//logo.png', since 'b.blend' and 'logo.png' are in the same directory. Instead, the filepath of the original Image object is copied without change.
