How to download captcha if there is no link to the image?

Question

PHP

I get an error with captcha https://api.vk.com/captcha.php?sid=618089329524&s=1 and I want to put it in rucaptcha for auto input, but how can I get an image with captcha? There is no link to the image

Answer 1

What do you think this is?
PS. It is better to save and send an IMAGE, not a link, it is possible to bind to an IP address.

Answer 2

This is the link to the picture. See image/jpeg for headers

Try my module, it is busy downloading captcha if required or works with base64
