i've had a lot of trouble trying to send jpeg to a server with base64 encoding. It seems that flash only allows the first four bytes of the byte array to be sent when it is a jpeg.
Anyone else come across this issue? I'd like to not base64 encoded/decode if possible. --- In [email protected], "netdeep" <deep...@...> wrote: > > > Can the data not be passed simply as a ByteArray instead of a base64 string?
