The service provides a simple way to capture and display a screenshot of the web page loaded by a specified URL. It retrieves a small preview of the page to be retrieved by clicking a link, helping site users to decide whether or not to open that page. It is intended to increase traffic to a site by offering attractive previews, which should boost click-through rates and site stickiness. The preview function is also intended to help users spot malware and other undesirable sites before clicking links that may compromise the security of their computers.
API methods support creation of a pop-up window with a preview image showing the destination page for a hyperlink in either of two sizes. Methods also modify links with "nofollow" attributes on destination pages to prevent use of irrelevant links to boost search engine rankings. The API performs a malware and phishing check on any previewed page and advises users of any security threats detected.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
