Ok, so I got the code to reload a new image every 15 sec. :
http://pwultra5.ci.stpaul.mn.us/cp_tiles/OpenLayers/OL.AVL.09-rlb.html
but I don't think it's display the new images, only downloading them (so far) .
. . getting closer though . . . nothing moving around right now, so, back to it
in the morning.
ended up taking a different route with things :
var timer=setInterval(Layer_redraw, 15000);
function Layer_redraw(){
mslayer6.params.counter++;
mslayer6.redraw(true);
}
var map;
var mslayer6;
var counter=0;
. . . .
var mslayer6 = new OpenLayers.Layer.MapServer( "<br /><img
src=\"http://gis.ci.stpaul.mn.us/datasets/DB/SAINT_PAUL/PUBLIC_WORKS/AVL/STREETS/plots_last_public.map?mode=legend\";>",
"http://gis.ci.stpaul.mn.us/datasets/DB/SAINT_PAUL/PUBLIC_WORKS/AVL/STREETS/plots_last_public.map?";,
{layers: 'mslayer6',
format: "image/png",
transparent: "true",
'counter':0},
{singleTile: "true",
transitionEffect: 'resize',
ratio: 1,
displayInLayerSwitcher:'false'}
);
