Problem with image on Click-To-Reveal Widget being covered by text blocks

Hi. I am trying to create one flip-card per slide with the click-to-reveal widget (since there are currently layout issues with having more than 1 flip-card per slide; see my previous post).

On the back of the flip card, in all views Desktop tablet and phone things look fine -- but the front of the card is bad news.

The text blocks interfere with the image, and editing/re-sizing the image doesn't help. Further, in tablet view, the image is automatically cropped and zoomed-in on, which I don't want.

Any ideas? Screenshots below.

Thanks!
