Logo paypal payment

Hello everyone I'm very new at using Dolphin I'm a all around Joomla guy but I like Dolphin alot. Here's my question is there a way to embed my company logo into the payment page for paypal? I know with other scripts I had to just upload the image. But when I make paypal the payment option I only get the email address that they will be paying to displayed. Any help would be very thankful.
