The internet has become 3 massive multi-user blogs, each largely consisting of screenshots taken of the other two. This kind of blows, and not just for the usual reasons that may spring to mind.
Images are a terrible medium for online communication! Not everyone online uses a monitor. Any messages contained in a picture is straight up unacceptable without alt-text. It also makes it harder to find and fact check sources, or to spread a thought or idea further than yet another image upload. Copy/pasting text is just plain easier than downloading and uploading.
If you're going through the trouble of creating an image post, take an extra minuite to copy/past (or even transcribe) the source text into the alt-text submission. It's not much, but it goes a ways to improving how we use this blasted network!

You're right that it appears to reverse title and alt-text from the commonmark spec. That might be a bug or unintended deviation.
I know @Edie@hexbear.net has tested post images through a screen reader, but I'm not sure if she has tested comment images. She might know more.
Edit: actually, it's not reversed in the source. It's just that browsers seem to like to show the title text rather than the alt text.
I took a look from a computer at the source. The fields are mapped properly, but:
And regardless of whether I’m looking from a computer or mobile, the alt text is hard or impossible to see, while the title text is potentially visible.
Yes, that is how it works. Title has problems.
