In addition to Dave's points there is also the legality to consider.
Images are often copyrighted (although images of digits are less 
likely!) and sites often have conditions of use that prohibit web 
scraping. Such sites often include scripts that analyze user activity 
and if they suspect you of being a robot may ban your computer from 
accessing the site - including by browser.

So be sure that you  are allowed to access the site robotically and that 
you are allowed to download the content or you could find yourself 
blacklisted and unable to access the site even with your browser.
