I haven’t had this happen yet, but it sounds huge for general accessibility! Sure, we should be able to add alt text to photos we send, but, as @firstname.lastname@example.org has been saying, our devices filling the the gaps is good news for everyone.
I was today years old when I learned Siri tries to announce the content of a photo when messages come through. 🤯
The photo below was announced as:
"a white & black analog clock on a white surface"
