The encoding table and the image data are contained in seperate
streams in the SWF files. Both streams start with <ff d8> and end with
<ff d9>. To convert that to "normal" jpeg data, you need to convert that
to a single stream.
In other words, you need to find the sequence <ff d9 ff d8> in the data and
remove it.
