You can, but there's no easy way to hide it when it's placed using Fluid Engine. Instead, place the image in a Code Block wrapped in a `<div>` - something like this:
<div class="payment-icons" style="text-align:center;">
<img src="https://images.squarespace-cdn.com/content/v1/627082fb22c34f331451d6b6/edb21702-9537-470f-a4a5-e349ea0d099c/Payment+Processor+Icons+1.png">
</div>
Then, with that Custom CSS snippet above, you should be okay to go.
