It corresponds to:
•the message "The modification date of this picture has changed since it was imported" displayed in the Usage dialog available from the Tools menu of QuarkXPress, or
•the Status: Modified label in the Links panel of InDesign.
This scanning message is only a warning, but, if not fixed, it will be matched by a corresponding run-time message during diary generation.
Removing this message
This message is issued at the time of scanning or inspecting and therefore is not updated until the next scan/inspection, one way or the other, even if the image file is later re-imported/updated in the current GridTemplate or Info Pages.
The only way to update/eliminate this message is to rescan/reinspect the current GridTemplate or Info Pages.
Other possible source for this message
This would correspond to the appearance of the message on the right when opening the InDesign document manually.
