Download images through screen scraper in folder

Hi
I have made a pattern to fetch the data from flipkart.com in which i also fetch the url of the respective image.But i want to download these image from flipkart.com to my folder as the script run.How can it possible through screen scraper.
Also when i fetch the data from flipkart.com which is near about 10 lacs then after running after some times in the log there is a msg shown "execution stop because full of 50 stack" and execution of scraping stops.Is this problem occurs because of screen scraper trial version or something else?
Please specify it.
Waiting for your kind response.

Pankaj, To download images

Pankaj,

To download images you will want to use session.saveFileOnRequest.

The stack overload issue you're experiencing is not related to your version of screen-scraper being a trial copy. Our trial downloads are fully-functional for 30 days.

To help resolve the stack overload issue please see the following.
