yeah, we sent them the soft copy with the subject line "" updated photo" and mentioned our situation. Luckily they accepted it.
example:
Sub : UPDATED PHOTO---- APP# E00XXXXXXX
Dear officer,
I have just realized there is an incorrect face size for the photos I had sent to you along with the Passport, request letter and other documents in the package with the tracking number : 20211124INICPKTXXXXX.
So, to avoid processing delays , I went to the other photo studio to get the correct photos and am sending them to you.
Please attach them to our file and notify the processing officer.
Thanks for your time and consideration.
Attach the following docs : Soft copy Front and back of photo(Front : height of face 34mm , Back: requested details like studio details , date of photo taken, applicant name and DOB ), Request letter, eCOPR of principal applicant (if you have),
