I think the image window just needs to be bigger. It's so darn small and it feels a bit ridiculous. If it were bigger and easier to see I feel that would fix a lot of the problem and should be one of the easier things to code.
while i agree the captcha is too small, making it bigger would improve things only for users whose browsers don't have a zoom function.
the problem is that the images
themselves are inherently inaccessible.

a recent example from the larger thread:

I don't have vision issues. Finding the dragon on this particular captcha was not easy. I cannot imagine how anyone with vision issues is able to try and do these captchas. I already have to have it zoomed in to find the dragons.
The fact that this has been an ongoing issue for several years is disappointing.
before i gave up on the coli, i had captchas like this all the time. i probably would have clicked on the citrine familiar. i can immediately tell that an item icon is not a dragon because they're square, and i know the axolotls aren't a dragon because they're axolotls.
the only other distinct shape left is the familiar, which is vaguely dragon-like (four legs, a head, wings). i would have failed this captcha.
i opened the image in photoshop and turned up the contrast as high as it would let me.

this makes the dragon stand out better, but it's still the least visible image in the entire captcha.
so i reduced the contrast of everything except the dragon

i think this represents the
absolute bare minimum for an even vaguely usable captcha. even this, i think, is terrible, too busy, and too misleading. but at least the dragon is actually Visible now.
the problem is the busy background. the problem, always, is that the dragons look so much like the background they're functionally invisible. ironically, because i used software to render the dragon visible, that means a computer would have an easier time identifying it than a human.
to be reliably accessible, the captcha would need to have a completely plain, flat-colour, uniform background that never changes. black, white, grey, pink, chartreuse, it doesn't matter. it just needs to always have that one background colour that is always the same in every captcha.
