More information will be posted on my Mac OS X software page soon.
Alexa Site Thumbnail
The Alexa Site Thumbnail web service provides developers with programmatic access to thumbnail images for the home pages of web sites. It offers access to Alexa’s large and growing collection of images, gathered from its comprehensive web crawl.
But with Alexa Site Thumbnail you pay for each downloaded thumbnail. With SiteCapture, there will be a one time shareware fee 🙂
