Graphic programs
High quality images can really enhance the look of a website.
A range of programs exist to edit
images, with packages like
Photoshop being popular.
There are also free
packages available on the
Internet like aviary.com
which allow you to edit
images at no cost.
It is important to check the pictures you use for
copyright. To avoid any issues over the ownership of
images, it is best to use and edit your own.

Presenting graphics on-screen
There are a number of factors to think about when presenting
graphics on a screen for websites.
Resolution – High resolution
(300 dpi) is used for print, but
the quality of web graphics is
limited by the screen they are
displayed on. Usually, 72 dpi is
high enough quality.
File format – Save graphics in
the most suitable file format,
usually a .gif, .png or .jpg.
File size – Keep file sizes small
so graphics load more quickly.
