@Ted can you repost this with alt text please? I'd like to boost it, but without alt text it's inaccessible for users who use screen readers
@ValouriousKnight Sorry, Valour, you will have to explain that to me. How do I do it?

@Ted so you should be able to click "Delete and re-draft" in the corner of the original Post and then you click the "A" or "Alt" in the bottom right corner of the photo and then "Set Caption" and describe what the image is of

So for yours I'd say something like "A white woman in a nurses uniform, holding a handmade sign that says" if you love the NHS, don't vote Tory"

@ValouriousKnight I’ll try. Don’t think the skin colour of the nurse is important though, do you?
@Ted it's a general convention to describe what the image contains, which includes human diversity.
