Website is colourschaircovers.co.uk, need header.php and footer.php to be created and code inserted in pages so only need to modify these files to modify header and footer.
Need to add larger logo: colourschaircovers.co.uk/logo1.jpg, the one you add will be 2 times bigger than this.
Logo will be added where current logo is now, new logo is narrower so I will send you 10 images, you will need to crop them to correct height and width, they will go next to logo and fade in/fade out.
Also, in main body, you can see dotted line division, this needs to be an inch to the left, so the side with the changing image is larger, you can crop new images and modify the javascript for this larger image.
You will need to add another page, About us, this can be done from the HTML code I think, but check site to confirm.
Also, you will need to add a 160×600 banner on left hand side, just use placeholder for now please.
