I add a image as a header and I have white gridlines appearing throughout the image. If I add the image just as an image, it is fine but if added through the insert header, it has the lines through it. How do I get rid of them?
I'm guessing it's because the image is bigger than the Header and encroaches into the data area !
You can readjust the size of the picture like this
Microsoft Office Excel 2007
Click the View tab.
Click in the header or footer section where the image is located.
Click in the &[Picture] text of the image.
On the Design tab under Header & Footer Tools, click Format Picture in the Header & Footer Elements group.
On the Size tab, adjust the size of the image to fit inside the header or footer section.
