How To Grab Captcha Image in AHK

Hi I'm stuck on getting the captcha image in AutoHotKey (say, from this page: http://www.sears.com/shc/s/nb_10153_...page?adCell=WF). I can open the page in an AHK web browser GUI (and get the source) but I don't know how to download the Captcha image since there is no explicit link to the image (all I can find is this: http://api.recaptcha.net/challenge?k...tJ3HPqlkl1kFEq). I would really appreciate if someone could help me with this. Thanks.

PS: I will pay you if you can teach me how to do this.

there are ways to do it

You can parse out the CAPTCHA URL by using some basic RegEx. It's pretty difficult if you've never used it, though, so you'll probably need to refer to some online tutorials about it.
