The site will now detect if you are using a mobile browser such as an ipad, android tablet, etc ... If it detects that you are, you will be redirected to the mobile viewer version of the site. This is a very simplified view of the gallery. It shows you the photo, the photographers name and the lens used. You can tap on the photographers name to see only pictures from that photographer or you can tap on the lens used to only see pictures taken with the lens you tapped on. The next update will include the ability to upload as well.
To bypass this and see the normal version, simply log in.
