Yes. You can create a custom block with HTML or just image and show it on any page and location you need.
- Go to Design -> Blocks and click new icon (+) at the top right corner of content area
- Select HTML type of block and fill all the details you need and add image in "Custom Block content "
- save
- Now go to Design -> Layouts and add your new HTML block to any place you want on the page you want.
As alternative, you can create data listing block with only 1 image selected from resource library (Paypal logo in your case) and add this to the page you need in the layout.
Done.
