Neural network (FANN) and images?

Question

Neural networks

Hi again!
I'm at the beginner level.
As a rule, all data in the neural network goes through incoming neurons (input). I'm testing images now. I made a person identification and it works mostly well, but of course it doesn’t always recognize, apparently more training is needed (I only had 100 pictures of human faces and 100 other different objects). I transmit images through thousands of neurons, for example, a 128x128 picture is 16384 neurons.
The problem is that I need all the images in that size.
How to do something dynamically if the incoming neural is always the same. What to do with big pictures and small ones?
How to go?
