eclick, I’ve had success doing what you’re doing using widget.
I added the image as content, then linked it over with the following code within free text on the widget:
<a href="https://www.***Wherever you want your link to point***">
<img src="***use the content link for your image***" alt="Tab_Slide_Image"></a>
Just a thought if you haven’t gotten it to work yet ??
