Image Set Properties
The Image Set Properties command opens a dialog containing a table of selected properties for images of an Image Set. You can also re-order the image set by sorting on the properties or by manually interchanging the image ordering. The changed order can then be saved to the Image Window. The re-ordering capability of this command is also available using the Image Set Toolbar (Ctrl+Q).
Open the Image Set Properties dialog using the Ctrl+I key or by clicking Image Set Properties in the Edit menu.
