Attached is a sniffed stream where packet 88 and 92 resepctively contains an
image which is dissected as PNG b/c the HTTP headers indicates this. However
the "PNG Signature" is "Gif89a" and the packet is marked as malformed.
Even if there's an error from the web site - should the dissector try to
heuristic detect a GIF image in such cases instead to mark such packets as
"malformed" ?
