Currently, searching for images on the web is based on the name of the image file and possibly the text of the page in which this image is placed. (cf. This doesn't help when the text and the image are not logically linked together. e.g. A picture about the prehistoric animals in a tarpit in an article on operating systems might not get picked (esp. if the picture is named img1.jpeg) if someone searches for "dinosaur war".

Searching for images on the web is primarily done for HTML/DHTML documents containing images. PDF, PS files containing images are difficult to index and are not covered by this invention as current technology doesn't allow for extracting images from within such documents.

The idea is to provide robots with more information about images available on the web. Current image search relies heavily on the image file name and the text associated with this image. webpage designers have no way of influencing the search engines beyond the mere handle on file name.

Providing web page designers with a means to qualify their images is the focus of this invention idea.

Qualifying images are based on a few factors. Some of them are to do with the nature of the content and some with the technical details of the image itself. Examples of the former in...
