How to add zeros by comparing the file sizes of the two images?
Suppose the first image is 240x152 and the second image is 240x168
And i need to resize the first image using zeros to the same as the bigger one that is 240x168
so how is it possible to do the same?

Try this
I = rand(240,152) ; // first image
iwant = zeros(240,168) ;
iwant(1:240,1:152) = I ;

Are you looking for this?
zero_matrix = zeros(240,168-152);
I = [zero_matrix,I]
