A quick and dirty method that may not always work is this:
IM=imread('li.jpg');
IM=IM(321:472,97:1106,:);%crop white field
IM_BW=mean(IM,3)/255;%convert to grey scale double
IM_projection=logical(max(IM_BW,[],1));
idx_end=find(diff(IM_projection)<0);%col index where a letter ends
idx_start=find(diff(IM_projection)>0);%col index where a letter ends
%This may not be true if the letters are kerned
distance=idx_start(2:end)-idx_end(1:(end-1));
split_col_idx=idx_end([distance>50 false])+1;%50 is a threshold distance
%split_col_idx contains the column where you should split the words
The result here is that you should split at columns 465 and 713 in the cropped image, which is indeed after the y and the s.

Experience. Learn from your mistakes and the mistakes from others. Muck about, just trying stuff. As long as it is not your job to develop Matlab code, it is OK to make stupid mistakes, so make them and learn from them.
(and if my answer helped you, please hit the button to accept it)
As for saving the separate files, check out the function imwrite. You can open the documentation by typing doc imwrite in the Matlab command prompt. If you are unsure of how to actually split the file, have a look at my second line of code. (that's another free tip: steal and adapt code from others (but do give them credit when you share your adapted version))
