Reducing Load Time Through Image
Optimization
Even though more and more Internet users switch to broadband
every year, a large portion of the web's population is still
running on good old dialup connections. It is therefore unwise
to count them out of the equation when you're designing your
website, and a very major consideration we have to make for
dialup users is the loading time of your website.
Generally, all the text on your website will be loaded in a
very short time even on a dialup connection. The culprit of
slow-loading sites is mainly large images on your website, and
it is very important to strike a delicate balance between using
just enough images to attract your users and not to bog down
the overall loading time of your site.
You should also go to a greater length and optimize every
image on your site to make sure it loads in the least time
possible. What I really mean is to use image editing software
to remove unnecessary information on your images, and thereby
effectively reducing the file size of your image without
affecting its appearance.
If you own Photoshop, it will be obvious to you that when
you save an image as a JPEG file, a dialog box appears and lets
you choose the "quality" of the JPEG image -- normally a
setting of 8 to 10 is good enough as it will preserve the
quality of your image while saving it at a small file size. If
you do not have Photoshop, there are many free image
compressors online that you can download and use to reduce your
image's file size.
On the other hand, you can opt to save your images in PNG
format to get the best quality at the least file size. You can
also save your images in GIF format -- the image editing
software clips away all the color information not used in your
image, hence giving you the smallest file size possible.
However, saving in GIF format will often compromise the
appearance of your image, so make your choice wisely!
