The
getimage function returns the filename of a
value set image. Based on the provided item or value set, the image filename associated with the
value will be returned. The
value is either a numeric or string expression, based on the type of the item. If an
item_name is used instead of a
valueset_name, then the function will search for the relevant image in the item's current value set.
The function returns a string containing the image filename, or a blank string if there is no value set image for the provided value or if the provided value does not exist in the value set.
