[racket] need JPEG files for testing "mediafile" library

If you would like to contribute a JPEG file from your digital camera (or 
cameraphone) as test data for a Racket library, please see:
http://www.neilvandyke.org/racket-mediafile/#%28part._.Contributing_.Test_.Files%29

You can also try out the library yourself with your files, with a 
program something like:

#lang racket/base
(require (planet neil/mediafile))
(path->mediafile PUT-PATH-TO-A-JPEG-FILE-HERE)
;; Or, if you're willing to wait for a lot of file I/O, try this:
;; (scan-mediafiles PUT-PATH-TO-A-DIRECTORY-HERE)

BTW, this "mediafile" library will be part of the RackOut living room 
appliance.  This library still needs more testing and refining, and some 
additional media types will be added, but the library might already be 
useful separate from RackOut, such as in scripts to manage your photo or 
music collections.
