I want to develop software like this for all websites. Please tell me the source code. Plaese --Sridharbsbu (talk) 10:53, 15 December 2013 (UTC)
For all websites? Not doable. Each website is special. Some have APIs that can be used to obtain image metadata (such as license, description, author, and so on), other don't and then you're limited to analyzing the HTML. The HTML of course differs from website to website, and so do the APIs, if any.
Flinfo currently can deal with Flickr, ipernity, panoramio, Picasa, Mushroom Observer, Insect Images, Invasive Species, Weed Images, IPM Images, Forestry Images, and LeMill. Did you have a particular website in mind?
