How to programmatically alter image URL & Links during submi

Ok I found where to make the change. It's in filemanager/browser/default/frmresourceslist.html at this function:

function OpenFile( fileUrl )
{
fileUrl = encodeURI(fileUrl);

//Path modification below
if (this is a link creation?????) {
var tempLink = fileUrl.substring(fileUrl.lastIndexOf("/")+1);
fileUrl = "default.aspx?page=" + tempLink.substring(0, tempLink.indexOf("."));
} else if (this is an image insertion?????) {
fileUrl = fileUrl.replace(/(.*)images/i,"images");
}

window.top.opener.SetUrl( fileUrl ) ;
window.top.close() ;
window.top.opener.focus() ;
}

What i'm having trouble with is the if-else statement. How can I tell if the current process is for a link or for inserting an image? i tried using oConnector.ResourceType but that didn't work. This is where the "Browse Server" button is clicked and you see your list of files. I'm interception is before it sets the URL (whether it be for a link or image location). Can anybody help?

Nevermind, I used a quick and dirty method.. just checking the extension of the file clicked. This will solve most people's notorious relative link AND image problem. Plus this works with every type of language connector since it's the html file, not the .php, .aspx, .asp, etc connector file. Enjoy:

function OpenFile( fileUrl )
{
//Modified function
fileUrl = encodeURI(fileUrl);
var tempLink;
var ext = fileUrl.substr(fileUrl.lastIndexOf("."),fileUrl.length);

if (ext == ".html")
{
tempLink = fileUrl.substring(fileUrl.lastIndexOf("/")+1);
fileUrl = "default.aspx?page=" + tempLink.substring(0, tempLink.indexOf("."));
}
else
{
fileUrl = fileUrl.replace(/(.*)images/i,"images");
}

window.top.opener.SetUrl( fileUrl ) ;
window.top.close() ;
window.top.opener.focus() ;
}
