Binary Code in a Variable

Is it possible to load a variable array with binary code? In particular, I want to load profile photos into an array and assign them as needed. Thanks for any guidance.

Do you mean something like

$Pictures = [System.IO.File]::ReadAllBytes("C:\Users\user1\Pictures\picture1.jpg"),
[System.IO.File]::ReadAllBytes("C:\Users\user2\Pictures\picture2.jpg"),
[System.IO.File]::ReadAllBytes("C:\Users\user3\Pictures\picture3.jpg")

@Curtis, that is exactly what I needed. Thank you!
