Koinup was a free service, allowing members to upload up to 1.5
gigabytes of photo and video content. As of 2008, Koinup did not offer a paid premium plan. Uploaders could add
tags to their entries and create photo or video galleries. Uploaded content could be shared either by embedding
web widgets on websites, or by using a set of
social media sharing tools. Koinup also featured tools aimed at creating a bridge between virtual worlds and the website. These tools allowed users to interact with their Koinup account while they are in virtual worlds. Particularly, members could send postcards directly from the clients to their Koinup galleries without leaving the virtual worlds. One of the most popular features on the website was the Koinup Places Section. Koinup Places allowed users to
geotag virtual world locations and upload them on Koinup. This feature created a user-generated directory of the best places hosted in virtual worlds. According to a publication in 2008, more than 1,000 virtual places have already been suggested by the Koinup community. On April 22, 2010, Koinup expanded their service by launching a paid application on the
Nokia Store featuring wallpapers of virtual world related image content. With the launch of
Metaverse Wallpapers on March 11, 2011, on Apple's
App Store, a similar application became available for
iOS devices. ==Interoperability==
