IMAGE is used to display image files in the input region of a TABBED PANE or in the DIAGRAM region.
Currently, there are three file formats that can be imported into an EASAP, and they are:
Before an image file can be rendered in an EASAP’s user interface, the file must first be uploaded from its current location onto the EASA Server and into the appropriate EASAP folder. This uploading process is accomplished using either the Files selection under EASA→Author→Authoring menu or the Files Tab in EASAP Builder.

All image files (.gif, .jpg, .png) have an existing width and height. If you want to maintain an images’s aspect ratio, you will need to know the existing width and height, and then set the IMAGE Size: parameter using width and height having an equivalent ratio.
If your imported images are being distorted unacceptably, set Define in Pixels: parameter to maintain the original resolution of the image file.
If an imported image is to be used in conjunction with a native DIAGRAM, then you will most likely have to specify the Origin: and Size: parameters using expressions containing the same object references used in the native object parameters.
Note: If you specify the size of an imported image in pixels, then all other DIAGRAM's need to be sized relative to the number of pixels in each direction.
