edit till your hearts are content. How do you post a raw?
First off, could you turn on 'Image Editing OK' under 'Edit Profile' in the User CP?
I found the easiest way to post a raw file is with Dropbox. It's free. Upload the file, and post a link...
The jpg may look like crap, but it'd be best to work on the raw.
edit: And you've got downloading disabled on your flickr.
