Remember that with OpenLayers your map is still getting snapped to the resolutions that you are being used by the cached layers and that the bbox will also be adjusted to match the height/width of the image.<br><br><div><span class="gmail_quote">

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>
