You have a great photo of the baby you want to include in your website, but a tree in the background looks like it is growing out of the top of her head. Or...you have, say, 10 photos you want to show on the page but if you put one photo above the other your site visitors have to scroll up and down the page to see all of the photos.
These are the problems a web designer must solve so your site looks great and is easy to use by your visitors.
The links to the right show examples of solutions to these problems. Just click on the link and watch the magic.
