Re: Slow image download in PTViewer/IE

Hello everybody
I did check if the script* as an effect on loading speed with IE, my
conclusion is it has no effect what ever the size i put in the script or
the file size, on a macintosh.
Off line, on a G4,
Applet with hotspots and scripts, or applet with a clean page and no
hotspots
• 1600*800 file
Netscape 4.72 6 sec
Internet Explorer 5 14 sec
• 3800*1900 file
Netscape 4.72 20 sec
Internet Explorer 5 48 sec
It is always the double in IE5 …
But the most ennoying problem, as i said before, i that Netscape memory
will grow each time you reload the applet !
With the big file it grows of 50 megs for each loading…
And the good news is the big file pans quit fast in Netscape …
* Helmut's script used
<script language="JavaScript">
if (navigator.appName != 'Netscape')
document.write('<PARAM name=maxarray
value="5000000">');
</script>
I tried 5 000 000 and 50 000 000 …
Best Regards
Denis
