Hi Pinoy, 

Of course, you can show it.

In our demo, we cut each payment method icons and upload it to Settings - Files

After that, copy the link of images and paste them into the HTML text like this screenshot below

<div class="image-wrapper">
<a href="#"><img src="{{ Link of payment image }}" width="" height=""></a>
<a href="#"><img src="{{ Link of payment image }}" width="" height=""></a>
<a href="#"><img src="{{ Link of payment image }}" width="" height=""></a>
<a href="#"><img src="{{ Link of payment image }}" width="" height=""></a>
<a href="#"><img src="{{ Link of payment image }}" width="" height=""></a>
</div>

Or you can upload an image of the payment method in the footer.

Best regards,

Shopify Team
