How can I save images in a loop?

Hi.. I'm working on a project that can crop individual lines from a document image. So far, I have achieved the cropping but I can't write a code that can save the cropped and remaining lines' images in every loop. Can anyone help? Below is the code I'm using:

function [fl re]=lines(im_texto)
% Divide text in lines
% im_texto->input image; fl->first line; re->remain line
im_texto=clip(im_texto);
num_filas=size(im_texto,1);
for s=1:num_filas
    if sum(im_texto(s,:))==0
        nm=im_texto(1:s-1, :); % First line matrix
        rm=im_texto(s:end, :);% Remain line matrix
        fl = clip(nm);
        re=clip(rm);
        %*-*-*Uncomment lines below to see the result*-*-*-*-
        %         subplot(2,1,1);imshow(fl);
        %         subplot(2,1,2);imshow(re);
        break
    else
        fl=im_texto;%Only one line.
        re=[ ];
    end
end

function img_out=clip(img_in)
[f c]=find(img_in);
img_out=img_in(min(f):max(f),min(c):max(c));%Crops image

print() or saveas() or use the File Exchange contribution export_fig .
