I would like to introduce an easy way to download lots of pictures from websites that name them sequentially, meaning they simply add a number and maybe some chars to every new picture added. Smugmug for instance uses one directory /photos/ on their website and puts all pictures, or at least links to them in that directory. All pictures look like number-M.jpg which makes it very easy to use a script to download all pictures within a certain range.
Private Galleries can be accessed at Smugmug
If you would use an image host, put up some of your images and set them to private, would you expect them to be still accessible by anyone ? This is apparently the case over at Smugmug where a private setting simply means that the pictures and image galleries are not directly linked from the homepage anymore but can still be accessed by simply entering the url directly in the browser address bar or download manager.
