Working with the ImageCollection plug in, I am seeing some wierd
behavior inside of the OpenLayers viewing window, but I am not sure
where it is coming from.
Here is a URL that demonstrates the problem:
<a
href="http://linuxdev.lib.berkeley.edu:8080/geoserver/UCB/wms?service=WMS&version=1.1.0&request=GetMap&layers=UCB:images&CQL_FILTER=PATH='furtwangler/17076013_01_0025a.tif'&styles=&bbox=0.0,-65536.0,65536.0,0.0&width=512&height=512&srs=EPSG:404000&format=application/openlayers">17076013_01_0025a.tif</a><br
/>
This image will display in the upper left corner of the OpenLayers
window. Moving it into the center of the window, I can zoom twice
before losing the image. If I switch to tiled, or if I change the width
and height, I can zoom a couple of more times, but I start losing the
images.
Could anyone tell me what's going on. I am not getting any
Javascript errors on the page nor am I getting any errors in the tomcat
logs.

Steve -
Thanks for your reply, but when I use
'format=application/openlayers' I am getting the Geoserver
OpenLayers configuration. There is no substantial difference that
I can see between the CSS in the windows. I am attaching them in
case anyone can see what's causing this.
Indeed it's not related to CSS, but to how the image collection plugin
works.
The plugin is meant to display as a single layer a large number of
small, non georeferenced images,
and all the images, regardless of their original size, share the same
bounds (since GeoServer sees
that source as a sort of mosaic, you decide which particular image to
get by using a filter)
This means in particular that you will not get the image to be
centered in the visualization if
it's smaller than the "shared" size.
There is some docs about the plugin here:
