When you select visuals for your website, you should make sure that they relate to its topic. Unrelated visuals may confuse users or make your website look less authoritative.
When you design visuals for your website, remember the types of internet access that your intended audience has. If your website appeals to high end users that connect to the internet via a DSL modem, then you can use large graphics. If your audience accesses the internet through a phone line, you should use small graphics so your website will download quickly.
Be consistent when using visuals throughout the website. Make all menus, titles, etc. look the same to add continuity to the website.
