Oh, you don't download anything. Sites like Photobucket and Flickr are just websites. You upload a copy of your picture to them and they store it and provide a URL or IMG code to the picture. They are set up to store such things, whereas this site is not. Attachments take up storage space in the database and can make it slower to use. I use Photobucket and it's free, which suits me just fine. All of them are trying to be more 'social' like Instagram, which is annoying, but they still work for what I need.
