image/pjpeg vs. image/jpg MIME types

If you got into this nasty issue that IE uploads your jpeg images as pjpeg (progressive jpeg).

My solution was just to ignore it when displaying it, since for instance I was displaying it on an rdlc report which does not support pjpeg


SELECT 
   CASE WHEN U.SignatureContentType = 'image/pjpeg'
       THEN 'image/jpeg' ELSE U.SignatureContentType END SignatureContentType,
   U.SignatureFileContent,..........
