I see at least the paths are incorrect to your images.
Probably your templates have the wrong path also.
I would suggest you start over.
I would say you need to transfer your existing version to your test server first. Then follow the upgrade instructions.
I know at least the styles are saved in the database. So you may find it is more difficult to fix your sql tables than to start over.
