When I open your page, map2 is giving me a different max extent. <br>
If you want to display exactly the maxextent and nothing else, then<br>
you're right to set the maxextent and ratio as you've done, but you'll<br>
also have to set the dimensions of the map div itself to be the same<br>
as those of your maxextent. This is not the case right now. <br>
<br>
The ratio parameter for the untiled layer is relative to the size of the <br>
map. <br>

<br>wms2.ratio = 1; <br>map2.addLayer(wms2);<br><br>Then, when I view the image location, the bbox is: -162.5,10.029297,-27.5,69.970703.<br><br>It's the same every time.<br>My site is at <a href="http://niceguy.wustl.edu/openlayers" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://niceguy.wustl.edu/openlayers</a>. It's a visual comparison tool for different emissions data. Ignore the big pink image if it's there. <br>The bottom two images should work where you can see the image request.
<br><br>Any ideas?<br><br><br><br>
