Web Site Graphics
Keep it simple..
I am not a graphics designer, so I cannot give you much advice on how to design your web site graphics for that ultimate look. Just make sure you don't waste too much time on developing your look, unless of course you enjoy graphics design. By all means, get some nice web graphics, but my experience is that it does not matter that much how the graphical design of your web site looks. It generally has minimal impact on the success of your web site. The only exceptions to this rule is if you are a top graphics designer or if your site looks extremely sloppy.
Keeping your graphics design simple has a number of advantages. Generally it looks better and more professional if you keep it simple. More importantly, however, simple designs tend to reduce the time you spend on maintenance of your web site, are likely to give the average web master better results in search engine ranking, and load fast enough to prevent your first time visitors from clicking away before they see what you have to offer.
When your web site and your design skills improve, you are likely to want to change your design now and then. Simple designs are easy to change.

Bloated graphics are known to drive away first time visitors. Make sure you compress your graphics and test how fast your web page is loading. If necessary, change the design so most of your web page is already visible to your visitors before your heavy graphics start loading.
