Image processing Questions

Hello to all,

 I have two questions related to image processing.

First question : I have some pictures taken with my digital camera and on
the pictures I have the date in red numbers on them. I would like to erase
those numbers from the pictures. I tried the procedure described on Wolfram
web site about image processing  (Removing text from an image). But it is
not working and I don't know why. Maybe some of you are doing it and could
share with me the procedure ?

Second question : I take a portion of an image using ImageTake. I do some
processing on that portion. Now I would like to put back that portion in the
original image. How can I do that? It would be like the inverse of
ImageTake... Any idea?

Thanks for any suggestions,

Robert
