Screen inoperable and flashes

Phone turns on, but screen flashes and the touchscreen doesn’t work. The keyboard will work. If you start typing anything the phone screen opens and if you hit mail (blue envelope) on the keyboard you can actually type a message and it will bring up contacts but I don’t know if I can send because I don’t have an acct anymore on that phone. I’m desperately trying to get my photos off of that phone, they are of my first grandchild. Is there a way or would you know what the problem is???
