Thanks DTlow for your fast reply.
En works very well OCRing names on inscriptions on headstone photos I have in it.
I read somewhere that there was a limit to the amount of pages you get
so figured putting multiples onto one page would allow more capacity.
I could have 3000+ photos so don't want to clog the system.
Do you mean using the Android EN Camera feature?
Using a DSLR and Lightroom, I could snap the photos much faster than the EN camera
and batch adjust the resolution down as I export and email them to EN.
Does resolution matter and is it trial and error till you get the best balance
between OCR working and file size.
