Sorry sorry, I was kinda vague.
Anyways, yes, all my pictures are saved as Gif files and I'm trying to do the same rain effect shown in the tutorial, as in animated rain, though I'm not coloring the rain, however when I add the noise onto the pictures and such, it just doesn't show up. Shows up on black as white, but it doesn't show up at all on my pictures. I figured it was meant to be like that until I merged it and nothing changed.
Anyways, I checked over all of the tutorial and found that I wasn't missing anything. I even tried to color the noise just to see if it would show up, though it didn't. I don't really know how to explain it any better than that.
