Captcha Image Format

[xboredx]

I was wondering does ZP send captchas in their native format or do they alter them to PNG before being set to a captcha service? I am using something custom and they are JPG files, but appear PNG after sent.

If so, is there a way to retain original file extension?

What's the reason for that?

What's the reason for that?

I made a captcha breaker, but for some reason it works perfect with jpg but not png. Just wondering if I need to rewrite my code or if there is a way I can easily switch it to send native format pulled directly from the server, such as in this case jpg.

Шэь not sure what you mean when you say that you made captcha breaker and how you interact with it from ZP. You can always use path to original pic if your code your own custom solutions.

Yeah that is what I ended up doing. I was sending using decapther.dll but replacing with 127.0.0.1, now I just download the image. For some reason sending using zenno seems to transform to PNG when the file is JPG. So it seems.

Thanks though, got it working!

ZennoPoster doesnt load initial picture. It makes screenshot of any part of the page that you set as captcha.
