Handling Google clientLogin Captcha Example

Question

I have a desktop application.

I try to perform authentication using

http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html

However, whenever I get a Captcha challenge, I use a HTTP GET request (I test using web browser) to get the image to present to user.

However, I always get the images :

Sorry, we are unable to handle your request at this time. Please try again later.

Any idea what I had did wrong? Thanks!
