When you post an image on the top left there’s a +alt option and there you can type in your alt text that’s meant to help people who are visually impaired or challenged.
You can keep it simple as to describing what’s on the image, or more intricate to highlight details otherwise missed!
In some cases (for me atleast) colours don’t always work as efficiently and if there’s computed text over a different colour background I have a hard time reading it or don’t even notice it, so its been a real treat to see what I’m missing out on with alt text!
