Yes you can upload picturesby saving or copying and pasting.
It is similar because you can share information with other people by showing them your website.
It is different because you can't put in animations, I prefer the site glogster because of moving animations.
You can post a URL without an e-mail. All you have to do is remember the URL. You can use your e-mail if you want to delete it.
