You can change this in the file "ajaxmappane.templ".
Around line 1666 you will find:
function RequestMapImage(reqId)
{
url = webAgent +
"?OPERATION=GETDYNAMICMAPOVERLAYIMAGE&FORMAT=PNG&VERSION=1.0.0&SESSION="
+ sessionId + "&MAPNAME=" + encodeComponent(mapName) + "&SEQ=" +
Math.random()
document.getElementById("overlay").innerHTML =
'<img class="mapImage" name="' + reqId + '" id="mapImage"
src="' + url + '" width=' + mapDevW + ' height=' + mapDevH + ' border=0
vspace=0 hspace=0 style="visibility: hidden; width: ' + mapDevW + 'px;
height: ' + mapDevH + 'px;" onload="return
OnMapOverlayImageLoaded(event)">';
}
Modify the "FORMAT=PNG" part to your liking. If you need multiple
formats, you could introduce a variable that the application sets.

Hi Jason
Any pointers on how to implement PNG8 or JPG for AJAX? Also, can non-tiled
maps be rendered like this too? My problem is a very very slow application:

I'm guessing that reducing the file size of the rasters will speed things up
a great deal.
Thanks
