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**
