What you're seeing isn't an image attachment, so there is no way to put an alt text on it. I didn't add any image, I just posted a link.
Your app or interface may automatically add a preview box of links in posts, which can contain an image from the website being linked to.

Hey, just to add, if you look further down this thread someone has told me how to add alt text to previews, and it works!
The original post's link may still show no alt text as the old version of the preview will still be in the server cache, but when the cache refreshes you'll see alt text on all links to fedi.tips (it may take days or weeks but it will happen).
So, thank you so much for raising this point because I'd never have found out about this alt text fix otherwise! 🙏
@FediTips Oh I’m so pleased! I’ll read the post. Thanks for alerting me.
If the linked site provides this tag, Mastodon is capable of passing the content along in the alt text of the embedded image. So it'd be up to you to add it to your WordPress theme or config, no idea how it works there.
It's technically a link preview, if you click anywhere on it it will take you to the link I included in the post.
I am not sure how accessibility software handles link previews, that's a really good question! Maybe @WeirdWriter knows?
Previews are not something under the control of the person posting. Not all apps or interfaces generate them though, some just leave the link as it is.
The logos in the illustration are: Fediverse, Mastodon, Pixelfed, PeerTube 🙂
It could get complicated as some previews may look different on different apps 😁
But it's great to help people out however you can 👍
