the number of images in the current team is returned. For values smaller or

equal distance to the initial team, it returns the number of images index

on the ancestor team which has a distance of <var>DISTANCE</var> from the invoking
|
team. If <var>DISTANCE</var> is larger than the distance to the initial team, the

number of images of the initial team is returned. If <var>FAILED</var> is not present
|
the total number of images is returned; if it has the value <code>.TRUE.</code>,
|
the number of failed images is returned, otherwise, the number of images which
|
do have not the failed status.
