Images detection with Microsoft explorer

I have an HTML file with an advertiser javascript tag inserting a banner in it.
I want to detect the name of the image file sent by the advertiser. The purpose is to detect the default banner when sent in order to redirect to another provider.

I used the following js code working fine with Netscape but with I Explorer I don't get any result at all (and no error msg too):

_imgcount=top.banner.document.images.length;
_imgsource=" ";
_found=-1;
for(i=0;i<_imgcount;i++)
{
_imgsource=top.banner.document.images[i].src;
if(_imgsource.search("flash-es.gif")!=-1)
{alert("FOUND flash-es.gif")}
}

Explorer is not able to detect any images sent by my banner provider with this code...
If you ever need more details to understand the problem, please contact me.
Any ideas?

Thanks to all.

By testing the code sent by the banner provider,
it seems that the banner image is embedded into an IFRAME
tag. Explorer detects the frames but when trying to get back
info on it with for instance a self.frames[i].document.images.length I get back an "access denied" response.
How can I just get this image.src value?

Just received 1 answer:

Quote: Try switching this line:
if(_imgsource.search("flash-es.gif")!=-1)

With this:

if(_imgsource.indexOf("flash-es.gif")!=-1)

OTHERWISE

try looking here, if you dig long enough, you can usually find the answer:
