legend iterator tries to print array prototypes as image sources

On line 200/201:

for (var idx in this._legendContainer) {
    var imgPath = this._legendContainer[idx];
        //...

If the Array prototype has been extended to have additional functions, those functions are returned by name as idx values. You then end up with broken image src attributes containing javascript source code from that function, for example in my case:

<div class="owm-legend-item" style="float: left; margin-right: 10px;">
<img src="function (callback) {
        var arrayClone, sections;
        sections = [];
        arrayClone = this.slice(0);
        $.each(arrayClone, (function(_this) {
       // ... etc
      }" border="0">
</div>

You could fix this pretty easily though with an isNaN check:

for (var idx in this._legendContainer) {
        if (isNan(idx)) { continue; }
        //...

PS: Thanks for the great plugin. It's super useful! I'll make a PR if you'd like me to fix this instead. Otherwise I need to fork it for the fix, as I need it soon.
