[n,m,p]=size(im1) % im1 is your image
n1=mod(-n,75)
m1=mod(-m,75)
new_im1=imresize(im1,[n+n1,m+m1]);

The FAQ code was specifically built to be general enough for situations like that, where the image is not an integer multiple of blocks. Please use code from the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F

Though you can resize using imresize() if you prefer to have equal sized blocks.
