Eight seconds – that’s how long a visitor on a website can
change his mind and click to another site if he is not contented
by your navigation. The cause of this may be your gigantic and
pompous graphics and photos. To keep visitors from turning their
backs away from your site, here are some viable remedies. Resize
the size of your graphics and photos, reduce its colors and save
them in a compressed file format.
In resizing your image or graphic, you can use image-editing
program to exact the size that you want to use for your website.
To do this, do not forget to include the height and width
attributes of the image because these attributes will tell the
browser what size the image should be thus, a quicker page load
will occur.
To reduce the size of your image, it is indispensable to
eliminate unnecessary colors. A graphics saved with three colors
is going to occupy a lot of space compared to a graphics with
200 colors. Thus, more color means bigger size.
Color banding will result when colors are already reduced. This
means that the areas where colors are eliminated will be filled
with solid bands of color. Dithering can be utilized to help
reduce color banding. Though, expect that your file size will
increase slightly nonetheless, it will help achieve quality
colors as well as graphics. This is a bit tricky to the eyes
since it creates an illusion of more colors in your image.
The last step is to save your image in the compresses file
format. You can utilize GIF or JPEG.
GIF is short for Graphic Interchange Format is a loss-less
compression. Here, when image file are compressed, data are not
lost. Nevertheless, available colors for this technique are
approximately 256. This is most commonly used in sketches,
drawings, small icons and less colorful graphics. When using
GIF, you must determine the quality of the image you can risk in
order to transform it in a smaller size. In this technique you
can set a transparent background especially in cases where you
wan to place an image on a gradient or patterned background.
Another technique is the JPEG short of Joint Photographic
Experts Group. It is saved in a 24-bit format and can be used
for millions of colors. This technique is a loose compression.
To avoid losing some data, save the original image in a lossless
format so that you can easily grab it for editing purposes. You
can use the Cache feature on the hard drive so that it can be
readily available when you need it.
Now you have a more accessible site! Expect a greater number of
visitors..
