Is there a graphical editor for building relationships between two or more objects (pictures)?

Question

Image processing

I have a small library of pictures
. I need to indicate the relationship between them. Usually I mark them with a line
But when there are too many pictures, the lines overlap each other, which makes me confused.

I need one end of the lines to move after the picture after moving the picture to another place.
This is necessary for more convenient construction of the relationship between the events that I mark with the picture .
Example.

I've used photoshop before, but it's not very suitable for this task.
I need something similar to this ezoterik.org/games/rasputat_linii.php
Only instead of dots a picture with text.
Yes, I know that the question is strange and specific, but maybe someone met such a program?
