One of the additional properties you should add to your image tag  <IMG ... >  is, giving the user a short hint as to what to expect of an image once it is loaded. You can do that by an "alternative title", coded as

	                         <IMG ALT=...   . . . >

If you have some sense of communication, you can word the "alternative title" such that the visitors can hardly wait till the image is loaded. You can, for example, entice their curiosity by announcing in the text something that "You will see in the following image:".

ALT=... is good also for those of your visitors who have the graphics switched off in their browser. From bad experience they know that many web sites have graphics that are not really needed, that are only eating up load time. So they switched it off completely. (Want to try it yourself? - Go to your system's control panel - click Internet - Advanced tab - scroll down the list of your browser's options - uncheck  Show Pictures - click OK button.)

Try it at one of your own pages. Soon you will see how disturbing it is if a graphic's "ALT=..." is missing. Save your visitors from that experience - provide ALTernate titles to your graphics!

ALT-texts are frequently used to make a web site more search-engine friendly. You can even use them to stuff an image with any number of keywords. Remember, however, that your visitors will see them while the image is still loading. So you should not go overboard - the keywords should still make some sense to them!
