{"edit":{"captcha":{"type":"image","mime":"image/png","id":"2050100762","url":"/w/index.php?title=Special:Captcha/image&wpCaptchaId=2050100762"},"result":"Failure"}}
So I use the url to try and download the image, but get nothing. Visiting the link in my browser gives
Requested bogus captcha image
Any idea what’s occurring?
