img = imread('face.jpg');
fid = fopen('pixels.txt', 'w');
if fid == -1, error('Cannot open file'); end
fprintf(fid, '%d %d %d ', size(img));
fprintf(fid, '%g ', img(:));
fclose(fid);

You can read back the file (just use your favorite internet search engine to find a myriad of people asking how to do so). You can then use reshape to shape it back to your original image.
IM_double=reshape(IM_from_file,48,48);
IM_original=uint8(IM_double);
