I need to create a custom look for the Google Maps info windows (straight-edge frame and transparency, etc). I understand this is only doable with an external plugin, but I am not sure which one to use.

I have tried to use extInfoWindow, but I have had problems with getting it to work properly.

I have also looked at PD Marker window (.asp), but it seems it has been a while since it has been updated (2007)

Are there any other plugins with similar functionality?

Thank you,

I had that problem myself. I've been using api v.3 and there was no really good custom infobox out there, so I made up one myself (based on a few that I've found). I hope it helps :-)

Here's the plugin code:

function InfoBox(opt_opts) {
    opt_opts = opt_opts || {};
    this.imgPath='img/infoBox/';
    google.maps.OverlayView.apply(this, arguments);
    // Standard options (in mon with google.maps.InfoWindow):
    this.content_ = opt_opts.content || "";
    this.maxWidth_ = opt_opts.maxWidth || 0;
    this.pixelOffset_ = opt_opts.pixelOffset || new google.maps.Size(0, 0);
    this.position_ = opt_opts.position || new google.maps.LatLng(0, 0);
    this.zIndex_ = opt_opts.zIndex || null;

    // Additional options (unique to InfoBox):
    this.boxStyle_ = opt_opts || {};
    this.infoBoxClearance_ = new google.maps.Size(1, 1);
    this.isHidden_ = opt_opts.isHidden || false;
    this.pane_ = "overlayMouseTarget";
    this.enableEventPropagation_ = opt_opts.enableEventPropagation || false;
    this.div_ = null;
    this.closeListener_ = null;
    this.eventListener1_ = null;
    this.eventListener2_ = null;
    this.eventListener3_ = null;
    this.contextListener_ = null;
    this.fixedWidthSet_ = null;
}

/* InfoBox extends OverlayView in the Google Maps API v3. */
InfoBox.prototype = new google.maps.OverlayView();

// Creates the DIV representing the InfoBox. @private
InfoBox.prototype.createInfoBoxDiv_ = function(){
    var bw, me = this;

    // This handler prevents an event in the InfoBox from being passed on to the map.
    var cancelHandler = function (e){ e.cancelBubble = true; if (e.stopPropagation) e.stopPropagation(); };
    // This handler ignores the current event in the InfoBox and conditionally prevents the event from being passed on to the map. It is used for the contextmenu event.
