Detailed Description

Image Widget.

The image widget is a widget that displays an image created either from a file or an image buffer. The only difference is that the client saves image buffer data, so many of the same image can be created quickly from a buffer. Also, image buffers can be pre-loaded to the client so that images can later be created without sending the pixel data.
Creating an image from a file is simple, and can be done from many different file types. JPEG and PNG are recommended, however, as other types may not be supported on all machines.
