Visual Studio Image Library: Common Elements (Objects)
Each .png file includes a transparent layer to allow for easy cutting and pasting into new images, and is made up of multiple sizes for each element. The way to preview these compound images is to use Windows Explorer and set the View to "Thumbnails".
Use Restrictions
These common elements are to be used in the development and illustration of
new custom imagery. As part of a visual language, these images (or any
part of the images) must be used in a manner consistent with the name of the
file, which is self-descriptive of the object that the imagery represents.
