Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
The alt text for an image covers the lower left portion of the image. Frequently there are words that are illegible because they're covered by the alt text.

Describe the solution you'd like
A clear and concise description of what you want to happen.
I'd like a way to have the alt text hidden. It could be that clicking on the alt text removes it, or having a setting to have the alt text start out hidden, and only show it when a button is clicked.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

1. Clicking on the alt text removes it.
2. A setting that starts the alt text hidden, and only shows it when a button is clicked.
3. Make the alt text draggable.

Is this on the timeline or when you click to see the image itself?

(not the OP but I run into this regularly too)

This is when you click to see the image itself, particularly on desktop.

Just tested on mobile, it seems just tapping the image again removes all additional UI so the image can be seen unobstructed. IMO it would be great if it worked that way on desktop as well. Looks like when I move my cursor outside the window, sometimes all the UI hides as well? So there seems to be partial functionality for this already, maybe just needs to work on image click on via another button.
