Recovering Photos from Old iPad

My little sister burnt through nearly the allotted attempts for an old iPad, then asked me to unlock it so that she could see some old photos. I did not know this, and was going to cycle through the 4-odd pin numbers it could possibly be, and was promptly permanently locked out of the iPad on the first attempt. It says "connect to iTunes," and when I do so on a computer iTunes refuses to work due to my not having unlocked the iPad. I do not know the old Apple Account information, and I do not know if the photos were backed up in any way (whatever automatic photo process iPads had 7 years ago, that's what was being used).

How should I go about attempting to view these photos?
