send a picture over TCP
I am using python 2.3.3 and have installed PIL http://www.pythonware.com/products/pil/index.htm
I need to send a picture over a tcp socket (jpg). I can't figure out how to do this. Opening the file using builtin open, storing it in a list. Marshal the list (dump =marshal.dumps(list)) and send it to the server. Then unmarshal it (list = marshal.loads(dump)), write the list to a file. Then pray it will be able to view it using xv doesnt sound as the right solution. Correct me if am wrong!
This can't be so hard to accomplish!?

Quick question here... why are you serializing the data. Why can't you simply send the raw image data over a socket connection. You could perhaps design your own little protocol if needed, something like this:
IMAGE <imagename> SIZE xxxx
<image data follows>
That way the other end knows what the file name is and what size it should expect. It can then stream the remaining data to a file. You can perhaps add a checksum as well.

you should read a nice little slashdot post on over coding... more than 10 hours = bad buggy code... that is unless you are drinking because somehow druken code always seems to compile.
