We have recently received reports that PayPal's checkout pages (for PayPal standard and PayPal Pro Express Checkout) are currently not displaying a custom logo/header image (which our sellers can upload via their E-junkie Seller Admin > Edit Profile screen if they have joined our Reseller program). This appears to be a general issue affecting all PayPal merchants who pass the URL of a custom header image to PayPal with every checkout (as we do), as confirmed in this discussion from PayPal's developer site forum:
If you already have a custom header image uploaded to E-junkie Admin, or if you upload one now, that should start appearing on PayPal's checkout screens as soon as PayPal fixes the problem at their end.
As a near-term workaround if you cannot wait for PayPal to fix their custom header issue, you may be able to set up a Custom Payment Page in your account settings at PayPal's end. To prevent "mixed content" security warnings in some buyers' browsers, you can use our free SSLpic service (http://www.sslpic.com/) to obtain a secure URL for your custom header graphic, which you can then use in your Custom Payment Page settings in PayPal. This help page on PayPal's site explains how to create a Custom Payment Page:
