We ingest a lot of images from external sources. I would like to assure that already ingested images are not re-ingested in the backend. For this I was thinking of generating a GUID based on image's stream as follows



public byte[] imageToByteArray(System.Drawing.Image imageIn)
MemoryStream ms = new MemoryStream();
return ms.ToArray();
I was then thinking of making this into a CLR (if at all necessary) then save the GUID with the metadata of the image in SQL server. Not sure how accurately unique that GUID would be.

Any inputs?
