Do use tables, if you like. You can use tables with or without borders. Or, you can create a table and place the images inside. Avoid using background colors or images unless you really need it. Most new designers of Web sites try to keep the design as simple as possible.
Content is what counts.
Add text and images liberally. Whenever you include material directly from a Web site, include the Web address as the source. Don't use all capital letters for titles or text. This is not a good design practice. Use bold or underlining when you want to add emphasis.
