When you're designing your website, it's easy to start loading
it up with graphics, creating images that you think look good
and piecing them together to make a design. While it's a
tempting way to do things, you have to try to avoid it as much
as possible - otherwise, you'll end up with graphical overload.
Why is that a bad thing? Here's why.
It Takes Too Long to Download
The first reason to cut down on graphics is that the more there
are, and the larger they are, the longer it will take each of
your pages to download. Now that many people have broadband
connections, they're much more impatient than they used to be
when it comes to waiting for pages to download: in most cases,
you have around five seconds before your visitors start hitting
the Back button.
What can you do about this, apart from using fewer pictures?
Well, you can also make sure that you resize your images in a
graphics editor so that their file sizes get smaller. If you
just resize images by specifying a width and height in HTML or
CSS, then they still take just as long to download as they would
have, without the extra time serving any useful purpose.
Also, you might want to consider turning on compression in your
image editor: JPEG files especially can often be compressed by
20-30% before there's any noticeable difference to the human
eye. Try out different formats and compression levels to see
what works.
It Gets Too Busy
If you've ever tried to use a site that has more than three or
four different images on the page at once, you'll know what I
mean by that. Your eye is forced to dart all over the page, not
sure where to focus: the page simply has too much going on at
once. Instead of making your site busy by loading it up with
graphics, you should try your best to keep it as simple as you
can.
One thing I would suggest is that you take a look at the front
pages of a few newspapers, and notice how they only ever lead on
one picture. Putting two pictures on a front page is considered
to be very bad: the reader doesn't know where to look. That goes
double for websites, where the viewable area is much smaller
than a newspaper page. Even if you have more than one thing to
say, it's better to 'go large' with one picture and then explain
the other things in text, next to it or below it.
It Distracts from the Content
Don't forget that most of the people on your site are there to
get information, not to look at your graphics. Too many graphics
will distract visitors from your content, or, worse, even hide
it from them, forcing them to look around before they find it.
Any time your graphics get in the way of people using your site,
you're suffering from graphical overload.
What's the solution to this one? You simply need to think about
whether all those graphics are really needed - the chances are,
they're not. Don't just add graphics because you think they look
nice. Every graphic on your site should have a purpose.
An Exception: Photo Galleries
If photography is the purpose of your site, then you obviously
shouldn't be afraid to put a lot of graphics on one page.
However, you really shouldn't just post large photographs one
after the other. Instead, you need to provide thumbnails:
smaller versions of each image, with the visitor being able to
click on one to make it larger.
This lets you fit more pictures on each page, and avoids
visitors having to spend their time and your bandwidth
downloading files that they don't want to see. You can even add
'back' and 'next' navigation to each photo page, so the visitor
doesn't have to go back to the thumbnails to see your next
photo, if they want to see them all.
