We have all been there, sat at our computer waiting for the page to load, then waiting some more, then waiting a bit longer. Sometimes they hang around, other times, because of our impatience they hit the back button and find another website at which to look at or buy something from. Loading times today are as important as at any other time in the speedy. However website designers and developers appear to pay less attention these days assuming that everybody has tremendous speedy connections and the hosting server can deliver everything at tremendous speedy speed.
Another process used by web designers is to make sure that the compression of images is adequate. Unless you have an online site showcasing something such as photography most images can be heavily compressed. For some images people cannot tell the difference between those at 60% quality and those at 80%. For this you need to experiment to make sure that you get the right compression and keep in mind that every picture is different. Fortunately plenty of professional level picture editors (e.g. Photoshop) let you preview images at different compressions alongside each other so you can make a choice based on appearance than guessing at a percentage to make use of.
In the event you follow these simple guidelines then you ought to be able to reduce the download time for your pages and hopefully provide speedy access to your site and prevent users navigating away through frustration.
