you can of course display diferent pages for different resolutions, but you can also put your content in tables (if it isnt already) and make the table elements sizes relative instead of fixed(sometimes you will want some td's fixed width but make at least one of them relative) by either using % sign or not setting width at all. I design for 800X600 full screen window and if the resolution is higher it will spread out to look better. i dont worry about lower resolution or less than full size windows at all. for example:
<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td width="46%" valign="top">
<i>"A gracious way station for travelers who appreciate a warm welcome and immaculate accommodations"</i>
<p>Built in 1872 in historic Lafayette,
this early colonial style home is listed on the National Register of Historic Places.
The proud white house with green trim is surrounded by lawns, gardens and two hundred year old native trees.
Painstaking restoration has left the interior with a new feeling,
while graceful architectural details and selected antiques recall another era.
Guests enjoy gathering around the living room fireplace or on the front porch,
where an old-fashioned swing awaits.

<td width="4%"></td>
<td width="50%" align="right" valign="top"><img src="front.jpg"></td>
</tr></table>
i like to get someone with a higher resolution monitor to look at it for me though and tell me how it looks(i dont like fooling around changing it on my PC)
