Question: What is image optimization?

Answer: The term image optimization refers to a procedure in which the overall size of an image is reduced so that that image will download quickly on the Web.

Standard computer screens display images at 72 pixels per square inch. By optimizing the image (using Photoshop or any other imaging software), the density of the data in the image (not the width or the height) is reduced to only what it needed to display that image satisfactorily on the Web page at 72 pixels per inch.

An optimized image will look the same on the screen as the original, but will take much less time to download.
