Get re-Captha image and submit form

Is it possible to get recaptcha images from a non-web application?

For example, I'd like to show an image (for exam开发者_如何转开发ple in jdownload), and submit text and see result in python or java?

Yes, it's possible. Since recaptcha works over normal HTTP, you will need to have your java or python application simulate the same calls.
