Your guests need to be reassured that they have not left your Webpages. Effective design requires a common motif for your entire site. You can use colors and images to tell a story, transmit information, clarify text, provide a visual change of pace, establish structure and unity, build an image, prove a claim, or create a mood. If your image does not do any of these, leave it out. Don't use images just because you can.
