It depends on your host server, if https is enabled on your server and the path to your logo is https://mywebserver/logo.png then that should work. I think this is more a question for the company that is hosting your website.
Hope this helps,
Understood. I will be hosting with Adobe BC.
So if have I got this correct... I need to creat a seperate page to my website with just the logo image and use that URL?

Your logo image file needs to be stored on a secure server. I am not familiar with Adobe BC, please post your question on the Adobe BC forum site. Once this part is done, and according to the PayPal reference that you provided in your previous post, you will provide this secure-image-url to PayPal. If this does not work for you, then please contact PayPal support.
