Dumpr lets you manipulate your photos automatically. Some of the effects include converting your images to sketches, wrapping them around easter eggs, making them look old, and putting your photo in a museum. You can upload images from your computer, use images in your flickr account, or even from the url of a photo on the web. The terms of service explicitly state that the site claims no rights to your uploaded data.
