Problem with Lajox highslide plugin

Hi guys!

Can you help with highslide plugin for ckeditor? I just installed it and it's just fine apart from one issue. It replaces original link to a picture with it's own putting into "href=" and "src=" link to the same file. I just want it to leave it like below:

<a href="my image.jpg" class="highslide" onclick="return hs.expand(this)">
          <img id="name" border="0" src="small image.jpg" />
</a> 

Probably it's a matter of changing $[3] variable (below), but unfortunatelly I do not know JS and I am quite poor in regexps too.

str = str.replace(/^|(<a\b[^>]*>)?\s*(<img\b[^/>]*(?:src=("[^"]*"|'[^']*'|\S+))[^>]*>)\s*(?:<\/a>)?/ig, function() {
    var $ = arguments;
    if ($[0].length) {
        return [
            '<a href=' + $[3] + ' class="highslide" onclick="return hs.expand(this)">'
            , '<img src=' + $[3] + ' alt="Highslide JS" title="Click to enlarge image"></a>'
        ].join("\r\n");
    } else {return JSVar;}
});

Can you help me?
