Encrypted image address in the browser?

Question

HTML

http://site.ru/captcha_question/445
At this address, the browser sees the image.
In the developer panel, you can copy the encrypted address of the image data:image/png;base64,iVBORw...
Where can I find this address manually?

Answer 1

This is not an encrypted address, but a data uri .
The picture is right in this src itself and is contained.

Answer 2

data:image/png;base64

This is not an address, this is the resource of the image itself in base64 format.
If you are trying to find hypothetical captcha files, then be sure that they are not on ftp, images are generated on the fly.
Where the captcha generation module is called, the image is sent to the browser from there.
