 <script src="ng-file-upload-shim.min.js"></script>
 <script src="ng-file-upload.min.js"></script>

Upload on form submit or button click
 <form ng-app="fileUpload" ng-controller="MyCtrl" name="form">
 Single Image with validations
 <div class="button" ngf-select ng-model="file" name="file" ngf-pattern="'image/'"
 ngf-aept="'image/'" ngf-max-size="20MB" ngf-min-height="100" 
 ngf-resize="{width: 100, height: 100}">Select</div>
 Multiple files
 <div class="button" ngf-select ng-model="files" ngf-multiple="true">Select</div>
 Drop files: <div ngf-drop ng-model="files" class="drop-box">Drop</div>

 </form>

Upload right away after file selection:
 <div class="button" ngf-select="upload($file)">Upload on file select</div>
 <div class="button" ngf-select="uploadFiles($files)" multiple="multiple">Upload on file select</div>
 Drop File:
 <div ngf-drop="uploadFiles($files)" class="drop-box"
 ngf-drag-over-class="'dragover'" ngf-multiple="true" 
 ngf-pattern="'image/,application/pdf'">Drop Images or PDFs files here</div>
<div ngf-no-file-drop>File Drag/Drop is not supported for this browser</div>
