Cut a .tiff image and save smaller parts with specified size in a new folder

Hello, i got a bunch of data set photos with size 2048 x 1536. I want to split photos from this data set, into new, smaller images with size 227x227. I want to save these new pictures in a new folder, but i don't really know how to do that. Size of these orignal pictures couldn't be divided by 227, and also i wan't to make them new files, so i think i can't really use the mat2cell() function. Does anyone have an idea how to do that?
