There alway needs to be 2 CRLF's after header info. So in your first example 
you only have one and the 2nd you have the extra <@purge.

also, I don't there there is a mime type called "application/jpeg" it should be 
"image/jpeg"

here is what I did for jpegs

<@purgeresults><@assign request$httpHeader 'HTTP/1.1 200 OK<@crlf>Content-Type: 
image/jpeg; filename="mithumb.jpg"<@CRLF>Content-Disposition: inline; 
filename="mithumb.jpg"<@CRLF><@CRLF>'><@var request$imagedata encoding=none>
