Thank you!I just uploaded the snap shot of the email i got from the photo studio which had their signature and date on it. Not sure if that is the right thing as I am yet to know. To be safe, if you are ok, I would recommend you to get the photo printed out and request the studio to write the details on the back side. You can scan the back side only and upload it but when it comes to the front, you can upload the digital copy which you currently have.
All the best!
Forgot to mention. They stamped the back of the picture with studio name and date. I'll just add the name and birthdate, take a pic and upload it. I hope it would suffice.
