Using these images will require the end user to give credit to the original owner and must follow the guidelines in the copyright agreement. Credit is given when the image is inserted into a blog, web site, visual media, or print similar to citing sources in a term paper or newspaper article. To help an individual find images there are many image search engines available. These operate by searching for images tagged or labeled with certain key phrases that the image search engine searches for. Along with the image search engines, image archiving stores images in multiple resolutions and sizes to be available to end users. The archives are set up in a database that stores the image data as well as meta data in a standard XML format. This means that platforms of any design can access and retrieve the requested information. Image archives also work in conjunction with interactive media applications.
