Open Banking UK Images

This is not a "coding question" by itself but is something that probably only devs have to deal with most of the time (let me know if there is a different StackExchange better suited for this question, I couldn't find it myself).

We are trying to implement a client for Open Banking UK and we are getting the list of banks with their info from a new Mastercard service but they don't give us images or URLs of images to display on our front end.

The use case would be something like: "You want to pay X money, select your bank from the list to do the payment" We display a carousel or something with the banks we get from Mastercard and then we begin the actual action of requesting the open banking consent and all that. Is anyone aware of any opensource or somewhere you can find the logo of each bank?
