So you need to make a photo with [item=157540] near several places.
Turn away from person/location you want to make a photo of and use quest item.
Then click 1-st spell. If nothing happened, try to switch location a little bit or turn around.
The maze part is easy if you just open the map;)
On beta this quest had some map phasing issues near the Upper square. Try to stay near the fence..
