Paypal Custom Payment Pages

Need help with my logo on the Paypal Custom Payment Pages

right now when you visit paypal payment page after checkout from my www.caseshack.com.au shop
the paypal page displays my caseshack logo as it should.

I now have a new shop with a different logo naturally using the same paypal account but when
people checkout now it of course shows the caseshack logo...I need to change the logo/image
on the paypal payment page for new new shop when they check out

(naturally the new shop has a it's own domain, email and own OC )

really no one knows or has the same issue?

another bump
