If you count things within each photo (example, the open windows in photo 1 = 6), then count that number across the writing on each one, you will get a letter. It spells out:
"YOUVE BEEN HERE FOR TWO DECADES"
1= Y (6 windows = 6th letter of 'SO MANY PEOPLE HERE!'
2= O (2 bedposts = 2nd letter of 'NO ONE KNOWS')
3= U (3 light spots = 3rd letter of 'YOUR BEST BUDDY!'
4= V (1 vase = 1st letter of 'VALENTINE'S DAY'
5=E (7 birds = 7th letter of 'CHURCH ENTRANCE')

7=E (4 pieces of paper = 4th letter of 'CAREERS HUMBLE BEGINNINGS')
8=E (2 lipsticks = 2nd letter of ''BEST FLAVOUR!')
9=N (9 bullet holes = 9th letter of 'HER DRAWINGS')
10=H (7 lit up windows = 7th letter of 'THEY'RE HERE')
11 E (6 is on the TV = 6th letter of 'HOW THE TIME FLIES')
12= R (1 pole = 1st letter of 'READY TO KILL IT!)
13 = E (3 water stains = 3rd letter of 'THEY MUSTN'T KNOW')
14= F (3 lines on the floor = 3rd letter of 'SO FAR FROM HOME')
15= O (2 boxes on wall = 2nd letter of 'FOUR MONTHS TO GO')
16= R (3 numbers = 3rd letter of 'FOREVER TOGETHER')
17= T (1 drop/1 IV = 1st letter of 'THE NEW CLOCK')
18 = W (11 tear stains = 11th letter of 'AT LEAST SHE WAS THERE')
19 = O (3 scratches = 3rd letter of 'WHOLE WORLD AHEAD OF US')
20 = D (3 marks in the bottom left, like scratches = 3rd letter of 'MADE IT!')
