Flickr has so many tools. Here's one that's easy and really enhances the viewing experience. Simply copying and pasting the BlackMagic code in a photo's comment provides a link that will open the photo with a black background. If you can copy and paste, you can do this. Check it out at http://www.flickr.com/photos/nosha/3277989393/. This looks like a regular Flickr page, but read to find the code and instructions.

Here's a sample.

I suppose now that Flickr displays an image on a black background when you click on it, this isn't that much help, but it would give you a nice background if you wanted to send someone a link to a specific photo.
