Summary• There are better ways to layout images than tables, for example,

CSS.

• CSS layouts for images will load faster.

• Less priority is given to data if it is inside a table.

• User experience may be poor if they find it difficult to print your information as it appears on page.

• When using external CSS style sheets, it is much easier to maintain visual consistency throughout a website.
