System.Image entity use in workflow

Hi, I have an project entity which is a generalization of System.Image entity as I need to store an image. How can I use that in a workflow as a workflow entity if its not a generalization of System.WorkflowContext. Is there any way to keep two generalization for one entity?

Hi Arpita – can’t you linka project image with a 1:1 association to the project entity? and the project entity becomes your workflow context?
