I used PHP file_get_contents($imageurl); to grab image for decaptcher API. The problem is that the image I fetch using that code and the one showing on my browsers are different, although they both are calling from the same server and calling the same exact image url. And the image itself is static (it got id associate to it) and if I refresh it will remain the same. Decaptcher itself have no problem cracking the captcha but it's a wrong captcha. Anyone experience this before ??
