I'm sorry, I'm not familiar with a "photo pass". Do you maybe mean the "fast pass"? The fast pass is pretty much just a line holder for you. It works pretty well if you take a moment in between rides and think 2 steps ahead.
Basically, some of the rides have a machine where you can swipe your ticket (tickets these days are a gift-card like card with the magnetic strip) and it will print you a paper ride ticket. That paper ticket cannot be used immediately. It will have a window of time printed on it that you are to come back. As long as you come back during that window of time, you go through the "fast pass" line instead of the "normal" line. It is much faster, but sometimes still involves a couple of minutes wait.
The trick is that you can only have one fast pass at a time. You have to use the prior one (or expires by time) before you can get another. Not all the rides have them either.
What we did was pick two rides in close proximity to each other. One with a fast pass and a time posted for the fast passes for about 45 minutes out, and one other ride. While the group waits in the non-fast pass ride's line, have one person in the group take all the tickets and go swipe them for fast pass tickets at the other ride and then come back and join you in line. By the time you get finished with the ride you are in the current line for, you can usually almost walk right into the fast pass ride.
As soon as you exit the fast pass ride, repeat the process. You can typically do about 4 rides in the time it would normally take for 2 or 3 doing it this way.
Each ride with a fast pass option has a display somewhere around the entrance with times posted for when you are due to come back for the currently being issued fast passes. So check those before you commit. Sometimes you have a big gap of time, and it can pay off to skip it and try that one again later, and get a fast pass somewhere with a shorter/closer window of time.
Enjoy!
