Discussions, the new message walls, and the in-the-works new comments all use Feeds for core functions. Feeds is effectively a separate platform from the wiki. Therefore, they do not share images. An image uploaded to the wiki is not available in Discussions and vice versa. What I am not sure about is whether or not an image uploaded to Discussions can be re-used in a different Discussions post or in message walls (or comments).

Some Speculation (not really relevant to the question): The images are served from the same image server but they are saved and accessed differently. It seems that even when tagging a page, the preview image is accessed via the same method as an uploaded image despite coming from the wiki. That seems to imply that perhaps every image can be accessed this way but I have no confirmation on that. The URL used by Feeds contains a string of seemingly random letters and numbers. That string happens to be the correct length for an MD5 hash. The issue is, even if that is correct, I have no idea how to figure out what gets used as the input. I tried the image name by itself and that didn't work. Given that the same system is used for avatars, perhaps the input has something to do with the user and timestamp of the upload?
