Can I import existing headers and edit
Absolutely. When you want to import existing headers and
edit those in XHeader, you need to use the "Load Image from Hard Disk" option.
When you click on the "Load Image from Hard Disk" button,
a new window will open, letting you browse to the folder where you have your own image.
Select the image from that folder, click on the Open
button and this will load the graphic into the software so you can edit it as needed.
