How many images are there on the web? No one knows exact figure. I have some data from photo sharing service as follows. Not all images on photo sharing services can be searchable, because some images are not open to public. Considering other photo sharing service such as Picasa and TwitPic and other sites that have images related news, shopping and travel etc, it may be said that four or five billion images are newly added to the web at least.
facebook 15 billion 220 million new photo per week May, 2009
flickr 4 billion 100 million new photo per month Oct, 2009
photobucket 7.5 billion June, 2009
Some images are piqued other people's curiosity such as images of Michael Jackson and Hudson river plane crash etc. Some images are too personal to be interested by general people. Photos of parties grab its participants' attention only, unless celebrities attend them. Obviously, the number of searchable images are important, but navigating users to their interested images are crucial as well. Some users are willing to see images related to shopping. Other users are eager to find images about latest news. Each user has different interest and we need to satisfy these variety of interests.
Current GazoPa.com is for general purpose use and is trying to satisfy as many types of people as possible. That's why we have filter options like news tab, video tab and flickr tab. It aims to be one stop solution to users. But we also think there should be specific type of sites that suit for specific demand. Besides improving functionalities of Gazopa.com, we're building special sites for specific needs. It'll be released at the beginning of next year. Stay tuned!
