That's an excellent question. I often create infographics for my poetry so I can display the words on artwork created for the poem. But, I was under the impression that infographics don't count toward read time. So, I always include the text of the poem as well – which is repetitive.
In that instance, it would be hugely beneficial if an image could be embedded in a text box for which our text/poetry could be directly typed into. I don't see that happening though. The platform seems more intent on reducing layout and design options.
