One of the preferred ways to do it would be like this: http://wizard.dyndns.org/new.htm That way the people on the slow modems only end up downloading a 21K file as part of the page. At 33.6kbps, that's 5 seconds... as opposed to having to download the entire 241K file which takes a whole minute. Give them a "low-res" option in case they have older equipment or medium interest, and give them a "hi-res" option in case they have broadband, or high interest... but as a default, you've made them happy because your entire page is completely loaded in less than 10 seconds. (Since I did this only as an example, I've purposely degraded the quality of the two larger ones to save on bandwidth... in "real-life" they'd probably be something like 125K and 225K) > > <A HREF="bemax.gif"><IMG SRC="BEMAX.GIF" ></A> > > > bemax.gif exists in that directory. BEMAX.GIF doesn't. But come to think of it... why have an anchor link to the exact same graphic as its anchor? Why not just put it inline and forget about the link? <IMG SRC="bemax.gif" width="428" height="99"> BTW, the width and height properties are not there to size the graphic, but to tell the browser the size ahead of time, so it can "set aside" that space and lay the page out before actually downloading the graphics. -- Steve Ackman http://twoloonscoffee.com (Need green beans?) http://twovoyagers.com (glass, linux & other stuff)
