However, before overloading the document with images, there are important issues to keep in mind.
Graphics require bandwidth to load.
The more graphics on a page, the more time it takes to display the page. Graphics that are large can take so long to load that the user might tell the browser to stop the transfer of data, and then go somewhere else, rendering the page ineffective in information dissemination. Also, users may choose to view your page with graphics downloading turned off. Your page should still make sense to them even without the pictures. Whenever you insert a graphic into a Web page, you should include a text alternative.
