[Q] Add text into image matrix?

Hi everyone,

This is what I would like to do:

(1) Use imread.m to load a jpg file into Matlab.
(2) Add one line of text (eg. the date of image file) to the
image.
(3) Use imwrite to save the modified image back to a jpg file.

I don't know how to do step 2. I know that I can use text.m
to add text to a figure. But I don't know how to add text to
a image (which is stored in a 3-D matrix).

Thanks.
