Update publish instructions and media tutorial
publish instructions are hilariously out of date
MULTIMEDIA: If your image exceeds 800 pixels in width or 500 pixels in height, it will be resized to these maximums. We suggest that you crop and resize your images yourself to obtain the results you're looking for; a variety of free (libre) open-source software is available for this purpose. If you need help converting your sounds or video to a compressed digital file, consult our tutorial page. We serve RealMedia via HTTP so you should encode your clip as single-rate, not SureStream. QuickTime should be encoded as fast start, compressed header. For playability of media files on mobile devices, upload videos as MP4s with H.264 encoding. For audio, upload MP3s.
