Express Checkout Dynamic
Image Integration
PayPal hosts the PayPal buttons and logo images that you use on your website. Using only
hosted buttons and images standardizes their appearance on websites that use PayPal as a
payment option, which is convenient for you and gives your buyers confidence that their
transaction will be safe and secure.
Dynamic Images
To use dynamic images, you must pass information to PayPal as parameters appended to the
image URL. Your unique ID tells PayPal whether or not you are participating in events that
require image changes. Other information you pass instructs PayPal on the types of images to
return.
If, for example, you are participating in a PayPal campaign that you have signed up for with
PayPal and you have passed the appropriate parameter information to PayPal, PayPal
automatically updates the image to reflect the campaign information. When the campaign is
over, PayPal restores the default image. You are not responsible for scheduling or making
changes to your website application code before, during, or after the campaign. Because you
set up the dynamic image, PayPal handles these activities for you.
If you require localized campaign images, you can have the localized button image display for
each country in which you participate. Simply assign the correct code for the country to the
locale parameter you append to the dynamic image URL. PayPal returns to the default button
image associated with each locale when the campaign is not available.
Configuring the Dynamic Image
To set up the dynamic image, provide the name-value pair parameter information in the image
URL. You can pass information in the image URL for each option.
