Options for storing images in viewports. 
Use Cache Image: The viewport image will be stored as a picture, so that the image does not have to be regenerated. This is handy for large, rendered images that can take time to generate. Update: If Manual is selected, the generated picture will be updated after you select Update Viewport Cache.The remaining options on this page control the quality and size of the generated picture.
