Sugar Learning Platform promotes collaborative learning through Sugar Activities that encourage critical thinking, the heart of a quality education. Designed from the ground up especially for children, Sugar offers an alternative to traditional "office-desktop" software.

Learner applications in Sugar are called Activities. They are software packages that automatically save your work - producing specific instances of the Activity that can be resumed at a later time. Many Activities support learner collaboration, where multiple learners may be invited to join a collective Activity session.

The Image Viewer activity is a simple and fast image viewer tool. It has features one would expect of a standard image viewer, like zoom, rotate, etc.
