    jpeg data in mbox files

    Does anyone know how to read the jpeg data embedded in email messages? Each, something that starts like this:
    Code:
    --Apple-Mail-4-620893417
    Content-Transfer-Encoding: base64
    Content-Type: image/jpeg; x-mac-type=4A504547; x-unix-mode=0644;
            name=IMG_0164.jpg
    Content-Disposition: inline; filename=IMG_0164.jpg

    Notice, the lines are broken at 76 characters and this *IS NOT* normal jpeg data such as you would read from from an HTTP response, but I can't find any info on the web...

    Doesn't this just base64 decode to binary data? Not sure about the line breaks though.

    Actually, from the Base64 wiki:
    MIME does not specify a fixed length for base64-encoded lines, but it does specify a maximum line length of 76 characters.
