You can share links to web pages, but not actual photos, videos, or links to specific photos or videos (links with extensions such as JPG, PNG, GIF, MOV, MPG, etc). If the photo/video is embedded in a web page, you can share the link for the web page. You can also share the links in popular photo and video sites, such as Flickr and YouTube.
Why doesn't Zholink allow the direct sharing of photos or videos?
Zholink is all about saving links with context. There are plenty of other great photo and video sites. Zholink provides greater context and organization of links with the help of web pages that contain a title, summary, and keywords. Photos and videos often lack contextual information needed to help sort them.
