I have an HTTP request to my c# application that generates a memorystream, I want this request to return that memorystream as an image just as if I were to go on lets say google.com/myimage.jpeg I want the image to be shown.

How do I return it exactly?

I assume that the MemoryStream is named ms and the image type is JPEG, then you can return it simply with
 
Response.ContentType = "image/png"
Response.BinaryWrite(ms.ToArray)
Response.End()

Open in new window

Oops, sorry, there is a typo in the contenttype, it should be "image/jpeg".

On response.end I get
"[System.Threading.ThreadAbortException] = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}"

Oh, the cause of the exception is here: http://support.microsoft.com/kb/312629/EN-US/

As it suggests, we should call the HttpContext.Current.ApplicationInstance.CompleteRequest method instead of Response.End to bypass the code execution.

Sorry for the mistake.
