It is a chance to familiarise your visitors with your brand even when they are away from your site.
Using an art package like Adobe Photoshop, PaintShop Pro or GIMP.

Create an image 16X16 pixels in size. Due to the size you should use as few colours as possible.

Save the image as an ICO file under the filename of favicon.ico
3
Upload the file via your FTP client or File Manager within the 123-reg Control Panel
