Image Challenge Locally stored images

You should find the Recaptcha's iframe elements screenshots at this folder. This code is always taking screenshots and overwriting the existing 2 files automatically. "src\test\resources\screenshots"

• imageFile.gif: That's the 3x3 or 4x4 image challenge box.
• imageInstructions.gif: That's the instructions for 2captcha.com workers. Example: "Select all images with crosswalks"

That's a junit-java-maven-selenium Webdriver project. Default Test folder is "src\test\java\tests\Recaptcha2Test.java" just right click on IntelliJ's project explorer window or run it from command line with maven command.

Warning:

I cannot guarantee that it will always work. However, I developed necessary implementations for possible scenarios. Response times from 2captcha.com should take between 30-90 seconds depending on your settings at 2captcha.com. https://2captcha.com/setting/percent_100
