Using graphics on your website (screen 11 of 17)

Why use graphics on your website?

Web designers use graphics because, when used well, they can enhance the look of the website. They create a relationship between your organisation's offline promotional materials and its online presence. Graphics, along with your text and layout, determine your website's look and feel.

But use graphics carefully and sparingly. Things to consider:

  • They can give a cluttered appearance to a site.
  • Too many graphics slow the time it takes users to download each screen.
  • They can create problems for users with special needs using voice readers.

As with any publication, the graphics you use on your website should be appropriate, and add to the screen's message. They need not be in colour, and they can range from photographs to simple line drawings.

You also need to be aware of your copyright(1) responsibilities. If you are using someone else's photograph or drawing you must have their permission to use it on your website. You are not allowed to download images from the Internet and use them on your site unless you have the copyright owner's permission.

Graphic Buttons

Graphics can be functional, and not only illustrative or decorative. Graphics are commonly used as hyperlinks(2) to take users to another screen or site. For example, a graphic can act as a link to take users to another screen or site, or another part of the same screen - like this graphic which will take you to our Home page.

Remember the message about  Gcolour(3) - colours can look different on different platforms and browser applications. Other colours 'bleed' when displayed on screen. Take these factors into account when selecting any graphic for your website.

Incidentally, some users turn off downloading graphics in their browser application. This means that all graphics, especially those that are navigation aids, need text equivalents somewhere on each screen.

Graphic elements and colour choices

You can obtain some graphic elements from the Web at sites such as GArtServe(4),  GTimo's WWW Gifs Gallery(5)GColor Maker(6)GFrameshop(7), GWebdeveloper's Library(8) and GTable Maker(9).

GLview Pro(10) is a software program which enables you to manipulate images.

Think carefully how you use these graphic elements. Backgrounds, for example, should not interfere with the readability of text - so avoid dark or deep colours, textures and pictures as backgrounds. Use a Gcolour(11) which works well with your body text colour. This might sound a little prescriptive but it still allows an enormous range of possibilities.

White text on black (or any lighter colour on a dark colour) is difficult to read if there is a lot of text. There is nothing wrong with a white background and grey/black text - think of your users first. Choosing Gcolours(12) is worth spending some time over.

GIF or JPEG?

Any graphic used on a website should conform to one of the two main standards: GIF (Graphics Interchange Format) or JPEG (Joint Photographics Experts Group). 

Both are ways of compressing files and allowing them to be viewed on any type of computer.

GIF files are restricted to 256 colours, but they are the only truly universal format, able to be viewed on all computers and browser applications. For images of the same dimensions, the fewer the colours, the smaller the file.

JPEG files are more popular than GIF files because they can be higher quality images with more than 256 colours. Most computers can handle JPEG files.

As a rule of thumb, illustrations that can be displayed well in 256 colours or less should be provided as GIF files, and illustrations like photographs that need more than 256 colours should be provided as JPEG files. Large illustrations with few colours should be provided as GIF files, since large areas of the same colour may not display well in JPEG files.

Graphics software

Creating graphics for websites requires graphics software. This can be assisted by a scanner which allows input of images into a computer.

If you want to learn how to use some particular software packages there are Gtutorials on the Web(13) on Photoshop, Paintshop Pro, Corel and other Ggraphics' development(14) applications. Most Web screen design will require a Ggraphics' package(15) to help you manipulate images. There are a range of them available.
