Alt tags are mainly used by people who cannot see images on your website. Im sure you remember the dial-up age when websites took what seemed like forever to open, especially the ones with a lot of images. Some browsers had an option to turn images off. This allowed websites to open much faster. In place of the images were alt tags, describing the image that was suppose to be there. Of course dial-up modems have become out-dated and a thing of the past so why are we still using alt tags?
