Is it possible to create an app that will copy image files from a internal memory location like /data without someone rooting their phone?
or somehow for the user to temporarily allow root access?
Will JAVA I/O work? is this the only way?

No, it’s not possible without root because apps don’t have filesystem permissions to read data directories of other apps. Temporary root needs some exploit or unlock command to be executed which may be scary for users. What are you trying to copy?
