DbCommandImageAccessorCreateGetFrameCountCommand Method

A command that returns the frame count for an image. If this method returns null, the frame count will be determined by decoding the image stream. If not null, this command should result in a single row dataset with the frame count in the first column. If the frame count is stored separately from the image stream, implementing this method can greatly increase performance (especially first access). This command should not be associated with any connection.
