FIELD OF THE INVENTION
 This invention relates to photography, and more particularly to organizing and displaying photographic images.
 Digital photography has gained in popularity in recent years, due to the convenience it offers. Digital photographs may be taken with a digital camera and saved to a personal computer or other information handling system. Further, with the advent of inexpensive scanners, print photographs can be scanned into digital form for storage on an information handling system. Those digital photographs may then be viewed on the information handling system, or transmitted by electronic mail or other means to another information handling system to be viewed by another user.
 Typically, digital photographs are saved as image files in a particular format, and are viewed via a software program that opens the image files and displays the photographic images on a display connected to the information handling system. In a typical graphical user interface, such as Microsoft's Windows or Apple's Macintosh OS, the photographic images are displayed in one or more windows placed over a desktop. Such windows each typically include a frame surrounding a client area in which the photographic data is displayed. The frame typically includes a vertical scroll bar on one side and a horizontal scroll bar at the bottom, to allow a user to move the photographic image in the client area. The frame typically also includes icons for minimizing the window, reducing its size, and closing it, as well as a menu bar at the top listing commands that a user click upon to display a menu beneath. The frame typically also includes one or more toolbars for performing image manipulation and enhancement, or other controls useful for handling the image in the client area.
 While the person who took the photographs and transferred them to the information handling system may be familiar with computer technology and the software program used to view them, other users of the computer or recipients of image files containing those images may not be. Indeed, some users may be uncomfortable with the information handling system and its use. When the photographic images are displayed in a window having the features described above, the user can easily become confused by the number of controls and their functions. For example, the user may be unable to determine how to control the window, or view additional photographic images in a group of images. Some software programs may also display different photographic images at different sizes, depending on the resolution of the image. This may be confusing to a user who does not know how to use the scroll bars on the window, or how to resize the image, in order to view the entire image. As a result, the user may simply give up, missing the opportunity to view and enjoy the photographic images stored in it.
 Images are presented to a user directly on the desktop of a graphical user interface in the stylized form of a picture stack, where the user can move among images in the stack by clicking on it.
 In one aspect of the invention, one or more images are presented to a user directly on the desktop of a graphical user interface. Multiple images are conceptually stacked together, and may be slightly offset from one another to provide the appearance of a stack of photographs. One or more of the images may have a border, to distinguish it from the desktop and from other images in the stack. Multiple images may be sized substantially the same, in the manner of photographic prints. By displaying the images directly on the desktop, the user is presented with a simple and familiar real-world model for viewing a number of images in a stack, so that the user can easily view the images in a straightforward manner.
 In another aspect of the invention, the user may click at any location on the picture stack to bring up a new image. The image previously at the top of the stack may be sent to the bottom of the picture stack, removed from the picture stack altogether, or otherwise handled. By allowing a user to click anywhere on the picture stack to bring up a new image, the user can easily move among photographs in a manner similar to looking through a stack of photographic prints.
 In another aspect of the invention, audio data associated with the top image in the picture stack is played automatically. The user need not make an attempt to determine if the image is associated with audio data, nor locate and manipulate controls in order to play that audio data. The audio data is played automatically to improve convenience and usability.
 In another aspect of the invention, a toolbar may be provided on the display separate from the picture stack. The toolbar may include controls useful to an advanced user, such as controls relating to image manipulation or transmission. In this way, advanced users can perform actions on the images within the picture stack, without complicating the interface for less-advanced users who simply wish to look at images.
 The invention will be more fully understood upon consideration of the detailed description below, taken together with the accompanying drawings.
