I have always wanted to have family photos hanging on the wall going up the staircase, and we finally do!!
Hanging photos is never as easy as it sounds, especially when wanting them to look even on an incline, like a staircase.
SO to make it easier for myself I cut templates out of newspaper that were the same size as each of the photos.
I then hung these templates with tape in order to easier 'eye ball' if they were at the right height and distance away from each other!
And, without using a level OR a tape measure I was able to hang them perfectly.
I definitely recommend the 'template' route, especially when doing groupings of photos, as even though it takes a bit more time up front, it saves time and frustration in the long run.
