Embedding code onto an image

Hi there, I'm trying to add a widget onto an image and am wondering if this is possible via code.  I am also not currently even able to embed the widget...

which is the following from a reservations company:

                    <link rel="stylesheet" type="text/css" href="https://onsass.designmynight.com/?background-color=%23fffccb&primary-color=%23fffccb&body-text-color=%23f8cbe4&outer-border-color=gray"><script src="//widgets.designmynight.com/bookings-partner.min.js" dmn-booking-form="true" venue="66b37bdce26b763527072e0a" hide-offers="true" hide-powered-by="false" search-venues="false" monday-first="true" locale="undefined"></script>
               

thanks very much

I think you can add a Code Block under Image Block > paste your code > then share page url, we can try some code to move Code Block into Image
