This tutorial is about how to make "digital images." All of the images on a web page are "digital images", existing as "image files." See the "Web Graphics" section for more on the types of image files.
An image file is actually a
file full of instructions which tell the computer how to create an
image on your screen. These instructions may say things like "make
pixel 32 of row 65 a bright red pixel" or it might say "draw a 2
pixel wide line from pixel 18 row 72 to pixel 95 row 320."
So you have a great picture of your favorite little brother that you want to share with the world. How do you tell a computer to make all the little pixels look like little brother?
There are two main ways to make a digital image. You can "digitize" an existing (non-digital) image, or you can create an image which is digital from the beginning.
Page 2 of this tutorial covers digitizing, and provides information about scanners and other similar equipment. Page 3 gives some basic information about hardware and software designed to create digital images. Page 4 attempts to demystify the very puzzling subject of "resolution."
And of course, you can take regular photos, and ask the developer to include a CD with your phots digitized for you, or you can purchase CDs of stock photos.
We have also included some good links on our links page where you can find more in depth information and resources.
