Double-clicking on a graphic or file icon in the Figure field of a reference will launch an associated application (determined by the file type and your operating system) and open the file for viewing or editing. It is the same as if you had double-clicked on the figure file on your computer desktop. Any changes to the file are saved for this EndNote reference.
When you double-click a figure file such as a GIF file, your SystemWindows will look for an image viewer like Paint or Photo Viewer to preview the image. The program used to create the file may not open.
