Creating a custom payment page allows you to co-brand the PayPal checkout pages with your logo and colors.
Log in to your PayPal account.
Underneath the My Account tab, click Profile;
Click My selling tools;
Locate Custom payment pages, and click the Update link next to it;
In the Page Style Name box, give a name to your custom page style. (It doesn’t matter what you put here, as long as it isn’t “PayPal.”);
In the Logo Image URL box, enter the URL of your logo image. Your logo image should be 190x60px and should be hosted on an SSL-secured (https://) site. If you do not have an SSL-secured site available to you, free alternatives (such as sslpic.com) are available.
In the Cart Area Gradient Color box, enter an HTML hex code representing the gradient color you want to use around the shopping cart section of the checkout page.
Click the radio button next to the new payment page style you just created, and click Make Primary. Your custom payment page style will now be used whenever buyers choose to pay with PayPal.
