Hi David,
if you want to use a loading image you can use OpenLayers.Control.LoadingPanel
(it`s a addon afaik).
I use it because I´m having similar task of yours.
best regards
Sarah

Betreff: RE: [OpenLayers-Users] Browser slow performance while
parsingOpenLayers.Vector.Feature features
Zac,
thanks for your response. I know IE sux, but 95% of our customers have IE6
installed, and they are not allowed to switch to another version or to get
other browsers.
I get the polygons from GeoServer from a wfs layer. They are complex polygons
with lots of vertices (parcels from cadastre) and I can't simplify the
features because we are on the task of online editing using wfs-t protocol,
so the edition must be accurate.
I'm just wondering if there is something that I can show, like a progress bar
or loading image, to tell the user this kind of operations will take a bit, but
I'm afraid is going to be difficult because of the browser program.
Any idea?
Regards,
Un saludo,

short answer, IE just sucks
long answer, you could switch over to a real mapserver engine
how dense are your polygons? generalising them might help a bit if they are
very dense
