Tom,
You can no longer restart the Image service? What happens when you try to start it? Does it gives you any errors, any messages? Or, according to this event viewer log, it tries to start, without success?
Did you make sure that Image has the proper admin credentials? Go in Workflow, in Tools->Configure Services, and if you have local system account, uncheck it, and enter the proper domain and user name. User must have admin rights, and should ideally be the same that you're using in your Windows session.
If that doesn't help, have you tried reinstalling Image? Does that helps? Also, if it was working before, what has changed? Did you update anything on your system? Did you do any changes to users permissions or to your network? Any hardware changes?
Let us know!
Regards,
