How about the @ syntax after the -F option to ask curl to find the content of a named file? curl is willing to perform the cat operation for you.

Putting the entire content of an image in the command line is sure to exceed someone's idea of a reasonable length limit.

I don't think -F supports a filename that is just a dash (-) which would tell curl to read from standard input but I'll bet there is a way to use your cat operation with a subsequent pipe into curl's standard input. I know it can work with an ftp server instead of an http POST into apache.
