How can i add one image into another

I have to do a program which the user select by mouse a music note, after this, the user will clic into a empty music partiture to add the selection note to the partiture. At the end, the user will save the finish image.

I don`t know how can i add the note image into the empty partiture image in a specific position.

Thank you very much in advance.

new_image = original_image;
new_image( newrow : newrow + size(noteimage,1) - 1, newcol : newcol + size(noteimage,2) - 1, :) = noteimage;
