How to check if node exists in angularJS?

<li check-last ng-repeat="image in dealerdetails.images"><img ng-src="{{image}}" alt="" /></li>

is always giving me at least one empty row.

JSON looks like this:

{ "coordleft" : "225",
  "coordtop" : "340",
  "images" : [  ],
  "land" : "DE",
  "mainpic" : "../files/bilder/image.jpgg",
  "url" : "http://www.google.de/"
}

I was trying it with AngularUI and

<div id="sliderwrapper" ui-if="dealerdetails.images">

but it hasn't worked.

Thanks!
