I'm taking a look at the FLR(M) guidance notes
here and it mentions the following;
9. Photographs For your application to be valid, it is mandatory to provide the following photographs:
- Two identical passport-size photographs of yourself with your full name written on the back of each one.
- One passport-size photograph of your partner with his or her full name written on the back of it.
- Two identical passport-size photographs of any children under 18 applying with you with their full name written on the back of each one.
The photographs you provide must also comply with the mandatory format requirements specified in the separate UK Visas and Immigration photograph guidance.
The application will be invalid if they do not. Please ensure that you place the photographs in a small sealed envelope and attach it to section 1 of the form as instructed there - and without any staples, clips, pins or anything else which could mark or damage the photographs.
The photographs will be checked against the images taken when your biometric features and those of any children applying with you are enrolled.
So do I need to do this? I can't remember If I had to do this on the last FLR(M) extension application.
