Graphics are the usual suspect on heavy pages. Either as a result of a highly graphic design, or a few poorly optimized images, graphics can significantly extend the load-time of a web page. The first step in graphics optimization is very basic. Decide if the graphics are absolutely necessary and simply eliminate or move the ones that aren't. Removing large graphics from the homepage to a separate gallery will likely increase the number of visitors who "hang around" to let the homepage load. Separating larger photos or art to a gallery also provides the opportunity to provide fair warning to users clicking on the gallery that it may take longer to load. In the case of graphical buttons, consider the use of text based, CSS-styled buttons instead. Sites that use a highly graphic design Cheap Penny Hardaway Shirt , a common theme in website "templates", need to optimize their graphics as best as possible.
Graphics optimization first involves selecting the appropriate file type for your image. Though this topic alone is fodder for far more in depth analysis, I will touch on it briefly. Images come in 2 basic varieties, those that are photographic in nature, and those that are graphic in nature. Photographs have a large array of colors all jumbled together in what's referred to as continuous tone. Graphics, such as business logos Cheap T.J. Warren Shirt , are generally smooth, crisp and have large areas of the same color. Photographs are best compressed into "JPEGs". The "Joint Photographic Expert Group" format can successfully compress large photos down to very manageable sizes. It is usually applied on a sliding "quality" scale between 1-100, 1 being the most compressed and lowest quality, 100 the least and highest quality. JPEG is a "lossy" compression algorithm, meaning it "destroys" image information when applied, so always keep a copy of the original file. Graphics and logos generally work best in the "GIF" Cheap Devin Booker Shirt , or more recently, the "PNG" format. These formats are more efficient than JPEGs at reducing the size of images with large areas of similar color, such as logos or graphical text.
A few general notes on other media are appropriate. Other types of media such as Flash or sound files also slow down a page. The first rule is always the same, consider whether they are absolutely necessary. If you are choosing to build the site entirely in Flash, then make sure the individual sections and elements are as well compressed as possible. In the case of music, I will admit to personal bias here and paraphrase a brilliant old saying Cheap Dragan Bender Jersey , "Websites should be seen and not heard." Simply, music playing in the background will not "enhance" any browsing experience.
