Need to label images/videos with table index number

[pjcross]

Working with a customer today, he selected a group of 7 co-located points through a rectangular selection, then did a selection action to pin first one image, then another different image, for each of the points. Since they were all co-located. the lines all were drawn to the top point in the stack. Although the 14 images could be moved to spread them apart for viewing, there was no way to tell which image was associated with which run. The point of the exercise was to view pairs of pinned images for each of the selected points, but there was no way to know which images came from the same run. At a minimum, I think that the index for the associated run/row in the table needs to be written in the image or video viewer frame. Although I'd originally thought that the line to the source point would serve this function, with the Latin Hypercube sampling, this problem with coincident points comes up frequently.
