Image Search Engine.
The image searching technology is similar to the websearching. But the spider crawler will take care of only images.
The keywords for the image search are based on the filename of the image, the link text pointing to the image, and text adjacent to the image. When the crawler encountered an image, a thumbnail will be cached along with the keywords and orginal url.
When searching for an image each matching image is displayed. Then when clicking on a thumbnail, the image is displayed in a frame at the top of the page and the website on which that image was found is displayed in a frame below it, making it easier to see from where the image is coming.
Implementation.
As in the websearch this can be do with the aid of Spider crawler. The cache should be cross checked with the orginal url periodically. This can be developed using .NET, PHP, and J2EE
