Unless I'm missing something, you can't "send" the picture to the server without uploading it. Unless you mean to read the file and parse the binary bits on the client-side, then send that as a string to the server. In which case, that's above my paygrade.
(If it can be done.)
If anyone knows of a website that can offer ColdFusion help that isn't controlled by neurotic, pedantic jerks* (stackoverflow.com), please PM me with a link.
* The neurotic, pedantic jerks are not the owners; just the people who are in control of the "popularity contest".
