I'm on level 19 and can't figure it out.

1st pic- a bunch of photos all layed out on a wall and you can see there shadow ahead of them

2nd pic- a long table with chairs on either side, all white

3rd pic-a bunch of flags at the top of poles

4th pic-a bunch of people with there hands up as if they are at a concert.

the letters i can use consist of: l, l, p, e, k, y, p, t, t, c, l, n

the word is 6 letters long and I know that the 3rd letter is E.

Plenty
