Whoa, wait. I think you're misunderstanding the point of binary mode. You _definitely_ need binary mode on when working with binary file formats like PNG. Otherwise, your operating system environment may do funny things to the file content like treat the 0-character (NULL) as a terminator, or try to transparently translate line ending sequences. Would I be better off converting the image to base64 prior to sending it to > the server, then decoding it on the server? > The socket approach is low-level: all you've got is a pipe that can send and receive bytes. It's _all_ binary from the perspective of the network layer. base64-encoding and decoding these bytes won't harm anything, of course, but I don't see it helping either.
