Err...sorry that was a typo.
I've had trouble sending jpeg images to the server UNLESS they are
base64 encoded.
I'd like to send the data from the bytearray directly to the server,
but for some reason it seems that flash is only allowing the first
four bytes that identify the binary as a jpeg file to be sent. On the
server side, I just get 4 bytes. So I've resorted to first encoding
the data in base64, then decoding on the server.
I know this can easily be done with cold fusion, or web orb, but we're
not using them.

Could it be a server issue that you had?

Anyone else come across this issue? I'd like to not base64
encoded/decode if possible.
