I do have my project set to 64 bit only. The file coming from the DB could either be a jpeg or bmp. Only happens on large files. Small files work fine. So I'm figuring it is a memory issue. Just don't know how to fix.

byte[] tImg = dr.Field<byte[]>("IMAGE");
Image imgO = Image.FromStream(new MemoryStream(tImg));  <----- Errors Here
imgO.Save(outPath, ImageFormat.Jpeg);
imgO.Dispose();

UPDATE:::: Let me re-phrase the issue. I am reading a BLOB ("IMAGE") from a database. It is in a DataRow (dr) The BLOB is over 30GB (hence why I need to write it out as a jpeg/bmp get it of the server. Writing it out as WriteAllBytes leaves it unreadable.

On what line does the error occur? What constitutes *"Large"* and *"Small"*? – Flydog57 Jan 22 '20 at 00:28
Is dr a DataReader? Why not use dr.GetStream()? – Jeremy Lakeman Jan 22 '20 at 01:10
Over 30 gb?! Is this using `System.Drawing` classes? I know for a fact GDI+ can't handle anything that large. – Nyerguds Apr 08 '20 at 00:03
