Perhaps resampling might work, in order to change the size:

Do when i use it i specify a specific number ???so that all images are reduced to this number?

I have no idea why your images must be of a certain dimension. One example might be if you're passing them into a Deep Learning network. Are you doing that? If not, why can't your algorithm handle any size image? Why do they have to be a standard size?
