List Image Keywords

The List Image Keywords command generates a catalog (or list) of image keyword values in a Table window. The table contents may be graphed, saved to a file, printed, or coped to the clipboard. See Arranging Report Data for details. Images and image sets can be displayed from the table by checking the boxes of an image set or by double-clicking on a specific image.

This command is executed using the File > List Image Keywords command. The command opens a Windows Explorer dialog like that shown below.

After Windows Explorer opens, navigate to the target folder and choose the images to list. Keywords are pulled from the image headers and listed in a table window similar to the one shown below:
