"view all" does not work as expected

[nudelkiste]

if a needle at the map summarizes multiple images there is an option visible called "view all".
e.g.: https://sfinp.de/album/plugins/rv_gmaps/mapl.php?/categories&box=49.485204,6.404966,49.489476,6.421073

well, this opens a frame with all those photos, great.
But:
when opening one photo of this set, and clicking on one of the arrows to go forward or backward, then it does not show the next photo out of the selection in the beginning, but simply the next out of all photos in the overal album. Not shure where and how this could be fixed, but I think it should be possible to simply navigate to the next picture out of the selection.
