For the average web site or blog most of the load time is a result of the images on the page, the bigger the image files, the longer it takes for the page to completely download.
To improve download time, professional web designers will go though an image optimization process where the images on a site are fine tuned via a balance of file size vs image quality.
The following picture of some nice juicy fall apples illustrate the process. The settings used to save the image were adjusted but it is not until you look at image 4 that a noticable degredation appears. In this case Image 3 would be selected having the best combination of low file size and image quality.
Although we use professional graphics software to optimize there are plently of free ulitilies available to do the hard work for you. My favorite is Net Mechanic ..here you can upload your image and it is presented in varous optimized forms. Pick the image that best suits your need, right click and “save picture as”.
