zennoposter and downloading captcha images

I know, i could go to their forums but i cant post a thread because i just signed up.

Anyway im trying to make a template where zennoposter automatically saves captcha images everytime i refresh the captcha but i cant command it to download the file from the actuall address as it just downloads a 1x1 .gif that isnt the captcha.
The only way i can save the captcha is to drag and drop it ontop my desktop.

How would i go about telling zennoposter to drag and drop the captcha image to a folder?

I can probably help you with that ... when I have time.
