How to Change PayPal Logo on Checkout Page

V1.5.0

I would like my customers to know they can use a credit card on PayPal, so I want to change from plain PayPal logo to the PayPal logo with the credit card images.

I know how to change an image, I just can't find where it is in my site files.

Current Logo:

I want to change it to this one from the PayPal site:

Thank you.

Never mind. I figured it out. It was in the payment module language file.

Hello:

I would like to do the same thing but don't know where to go to change it.

Current checkout page:

I would like to be able to change this image to a larger one from PayPal, which I can get. I would also like to know how to be able to let my customers know that PayPal is exclusive for my website. How do I include this verbiage with the image? I have tried contacting PayPay about this but they aren't the most cooperative, which is unfortunate, considering I am only using them.

I am using v1.51. https://www.petluxuryboutique.com
