THX very much. It works. Two more questions:

1. When I change the height and the width of the logo, changes the image resolution of the logo too? Or is there a special command in VBA so does the image resolution of the logo doesn't change but its height and wigth?
2. We use jpg and gif files ... is there may be a better image format we should use in our process of changing the logo with vba? Better means in this case that we don't loose quality of the image resolution.

THX for your answers.
