Never
use small images and stretch them to your custom size or you will
sacrifice image quality (blurry, distorted, and viewable pixels).
-
Images
saved or retrieved from the Internet should be the same size you want
to use them on your Web page. This will avoid any image
interpolation.
-
If
necessary, it is possible to make larger photos smaller without losing
much quality. However, realize that items like text might not be
viewable if made too small.
-
Remember
that the amount and size of images determines the speed at which your
pages download to local machines from server location.
-
If
you need to have man or large images on your site then images should
be saved in optimized for web format. Images optimized for the
web have a resolution size of 72dpi and are usually no more than 60KB
in size. These graphics will be excellent for viewing on a
monitor but will result in low quality printing.
-
If
you need high quality images on your site then you might want to
preload them or slice them so they load in parts. This will
greatly improve the speed at which they load when clicked upon.
-
A
good rule of thumb is to keep your targeted audience in mind when
deciding on image quality.
