Greetings, Kristina, and welcome to planDisney!
Thanks for coming to us with your question and I hope that you had a truly magical visit to the Disneyland Resort recently! I love making new core memories with my friends and family when we visit the Resort and I regularly use the
Disney PhotoPass Service to capture these moments so I can look back on them.
I'm glad to hear that you had a wonderful time on Radiator Springs Racers! It's not an uncommon occurrence to forget your picture but you have a huge advantage in that you still have the photo number. The first thing you can do is to try and
claim your photo in your MyDisney account. Sign in to your account first and then enter the Attraction ID number of your photo in the text field to link it to your MyDisney account. Once it's linked, you'll be able to purchase and download it!
If that is not your photo or if it can't be located easily, you can
contact the Disney PhotoPass Service and report a missing photo. Once you enter all your details, Cast Members will do their best to find your picture for you. I've lost items at the Parks before and I know they really do try their best to reunite you with your photos and items. If you need to go this route, I would recommend doing it soon as photos do
expire.
Kristina, I wish you luck as you try to locate your photo (did you win the race??) and I hope it's as easy as linking the photo. Please stop by again whenever you have more questions for us because we'd love to hear from you again! Until next time!
Have a Magical Day!
