Even though increasingly Net users switch to broadband every year, a huge portion of the web's population is still walking on nice elderly dialup connections. It is therefore unwise to count them out of the equation when you are designing your net site, & a major consideration they must make for dialup users is the loading time of your net site.
Usually, all the text on your net site will be loaded in a short time even on a dialup connection. The culprit of slow-loading sites is chiefly huge images on your net site, & it is important to strike a delicate balance between using images to attract your users & not to bog down the general loading time of your site.
You ought to also go to a greater length & optimize every picture on your site to make positive it lots in the least time feasible. What I mean is to make use of picture editing application to remove unnecessary information on your images, & thereby effectively reducing the file size of your picture without affecting its appearance.
In case you own Photoshop, it will be obvious to you that when you save an picture as a JPEG file, a dialog box appears & lets you select the "quality" of the JPEG picture -- normally a setting of 8 to 10 is nice as it will preserve the quality of your picture while saving it at a little file size. In case you do not have Photoshop, there's lots of free picture compressors online that you can download & 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 picture editing application clips away all the color information not used in your picture, hence giving you the smallest file size feasible. However, saving in GIF format will often compromise the appearance of your picture, so make your choice wisely!
