I'd suggest the following:
create the 2 custom functions
function runPeriodically() {
PMap.reloadTime = 60;
window.setTimeout('runPeriodically()', 60000 );
reloadMap(false);
}
function displayTime4Refresh() {
$('#displayrefreshtime').html('Time until map reload: ' +
PMap.reloadTime + ' s');
PMap.reloadTime -= 1;
window.setTimeout('displayTime4Refresh()', 1000 );
}
put them into a JavaScript file, like the custom.js under /javascript/
or a JS file under your '/config/.../' directory (all JS files there are
loaded automatically).
Add the 2 function calls under pminit.js->function pm_init() like
runPeriodically();
displayTime4Refresh();
For the display of the splash GIF add the line
showloading();
inside the function mapserver.js->reloadMap(remove) {
Then it should do what you want.
