When you intialize your map, pass it a "restrictedExtent" so that it will only show your area of interest. See this example :<br><br><a href="http://openlayers.org/dev/examples/restricted-extent.html">http://openlayers.org/dev/examples/restricted-extent.html</a><br>
<br>Also, it should be possible to use one of your vector layers as a basemap, rather than creating a layer that does nothing.<br><br>Lennox<br><br><div class="gmail_quote">On Mon, Jul 19, 2010 at 7:36 PM, Mike Purvis <span dir="ltr"><<a href="mailto:mike@uwmike.com">mike@uwmike.com</a>></span> wrote:<br>

What effect are you referring to? Why do you care to restrict the bounds of the layer if you're just displaying blank tiles?<br><font color="#888888"><br>Lennox</font><div><div></div><div><br><br><div class="gmail_quote">

<div>My Image layer is like so:</div><div><br></div><div><div> baseLayer = new OpenLayers.Layer.Image( "Image", </div>
<div><span style="white-space: pre-wrap;"> </span> "/static/img/gridmap.png", </div><div><span style="white-space: pre-wrap;"> </span> new OpenLayers.Bounds(0, 0, 3, 3),</div>
<div><span style="white-space: pre-wrap;"> </span> new OpenLayers.Size(600, 600),</div><div><span style="white-space: pre-wrap;"> </span> {});</div></div><div><br></div><div>
It's a 600x600 image, and the coordinate system of the map scales that from 0..3. Is there a straightforward way to get this effect with either of the two above solutions?</div>
<div><br></div><div>Thanks.</div><div><div></div><div><div><br></div><br><br><div class="gmail_quote">On Mon, Jul 19, 2010 at 5:10 PM, BMcBride <span dir="ltr"><<a href="mailto:bmcbride@chacompanies.com" target="_blank">bmcbride@chacompanies.com</a>></span> wrote:<br>

var nobase = new OpenLayers.Layer("No Basemap",{isBaseLayer: true,<br>
