Express Checkout User Interface Requirements

PayPal Button and Logo Images

To inform buyers that PayPal is accepted on your website, you must place PayPal button and

logo images in your checkout flow. PayPal recommends that you use dynamic images.

PayPal requires that you use Check out with PayPal buttons and PayPal mark images hosted

on secure PayPal servers. When the images are updated, the changes appear automatically in

your application. Do not host copies of the PayPal images locally on your servers. Outdated

PayPal buttons and images reduce buyer confidence in your site.

Express Checkout Image Flavors

The Check out with PayPal button and the PayPal mark image are available in two flavors:

 Dynamic image

 Static image

The dynamic images enable PayPal to change their appearance dynamically. If, for example,

you have signed up to participate in a PayPal campaign, PayPal can change the appearance of

the image dynamically for the duration of that campaign based on parameter information you

append to the image URL.

The static images cannot be changed dynamically. To participate in a PayPal campaign, you

would have to manually update the image code to change the image displayed and restore the

default image when the campaign is over. The only way you can have image management

taken care of for you is to replace static images in your implementation with dynamic images.

Express Checkout Images

The Check out with PayPal button is the image you place on your shopping cart page. The

US version of the image looks like this.
