Hello Peter,

Thank you for your message!

ViewBug and Flickr are similar however we also have some differences. ViewBug is a photo sharing website that is aiming to bring photographers together and promote their work. Our members also have the opportunity to sell their images, improve their creativity by creating challenges, joining contests etc.

Here is a great article about ViewBug and Flickr:

Have a nice day!
The ViewBug Team
