Hey hey there everyone!
Sorry for 'necro-ing' this topic!
I did kind of forget that I even asked for help on this forum, but I have read your suggestions and at least learned something new! 
In the end I ended up using MS PowerPoint because it had a feature to 'reshape each image' to a different shape (like a hexagon) of a certain size. I had found a hexagon grid online & it did take some time re-sizing it to have enough Hexagons total to put everything in.
I did actually find the final image just now, but I think that due to privacy reasons I can't share it!
I can try to quickly mask everyone's name's & pictures just to show roughly how it ended up looking in the end for those of you curious enough.
Okay, I hid all the personal information & made this half-hazardly.

The people photos were on the white hexagons with their names written in white color above/below them on the blue half hexagons. The last / bottom 3 hexagons I just filled with the university logo, faculty logo and a funny picture of the current 'master' / 'head' (the responsible person for the study program) of the faculty.
The headmaster (that's the word I was looking for) was really happy that he had made it into the collage that will probably stay on the university walls for a long time since there are actually very few pictures with him circulating around.
