Digital images and Web sites—it seems this should be so easy, yet it appears to be rather difficult. Part of the problem lies in the inescapable fact that placing an image in a Web site is just not like placing a photo in a photo album for the coffee table. You’re confronted by myths and realities, and the two seldom square. So, let’s take a look…
What You See Is Not Necessarily…
What you get. Web “pages” aren’t pages in the classic sense, of course. Particularly with this Web site, the information that appears to be displayed on a page is simply content called by the underlying code when you select a topic or content heading from a menu. In any case, everything that is displayed on the World-Wide Web is first rendered into a digital form. With photos, you’re not dealing with a classic photo but a digitalized image that consists of so many pixels in a mathematical file. What is a “pixel?”
A pixel (short for picture element, using the common abbreviation “pix” for “pictures”) is a single point in a graphic image. Each such information element is not really a dot, nor a square, but an abstract sample. With care, pixels in an image can be reproduced at any size without the appearance of visible dots or squares; but in many contexts, they are reproduced as dots or squares and can be visibly distinct when not fine enough.—Wikipedia

If you use a digital camera, you should study the user manual to find out how to set the camera to give you images you can easily and readily use on a Web site, if you intend to share your photos on the Web. Why?
