Everyone knows it and nobody likes it: when using the i-ways PayPal Plus extension for Magento 1 or Magento 2, payment methods from third-party providers often have no icons. This is not so much a problem with the i-ways extension itself, which merely displays the available payment methods as configured.

The problem lies with the payment methods, which often provide no option for adding an icon. A relatively small change to a JavaScript file can let you assign any icon to a payment method.

The exact change varies a little from case to case. If you would like this feature, contact me. I would be happy to help at a reasonable price.
