Old iphone is disabled no backup
I wanted to get old pictures off of my 6S, after charging I tried logging in and struggled to remember my 4 digit passcode. After only a few attempts the phone now says "iphone is disabled connect to itunes" from what I am reading it wants me to erase my phone to reset. The whole purpose of me wanting to getting the pictures off the phone is because I do not have a backup. PLEASE HELP!!!! I have years and years worth of photos on this phone. I don't even know how this "disable" setting got turned on, I never have had any of my phones set up to disable after a few failed attempts. Any advise would be so greatly appreciated. Thank you.
iPhone 6s, iOS 11
