Hi 

You can try writing a custom section with html code with images you want and include this section wherever you need.

Something like this

<style>
    .card {
        width: 50px;
        height: 50px;
        background: url("cmicons/pyfolder.svg") no-repeat;
    }
    .card:hover {
        background: url("cmicons/pyfolder-done.svg") no-repeat;
    }
</style>

<div class="card"></div>
