Lets know how to add a Merchant banner to your paypal payment page. Instead of displaying a company name or other info, its better to display a 720x90 banner image that implies to your business. To add a merchant banner image, follow the below instructions.
Please specify an image that is a maximum size of 750 pixels wide by 90 pixels high. Larger images will be cut to this size. The image you choose will appear at the top left of the payment page. We recommend providing an image only if it is stored on a secure (https) server.
Have fun now. Though I hate paypal, but for you guys I just provided the article. Cheers!!!
