No image field component exists. If you wish to preview image before upload, please try to use the filebox. The code below shows how to preview a image before uploading it.
<img id="image1"/>
<input id="f1" class="easyui-filebox" name="file1" style="width:300px" data-options="
prompt:'Choose a file...',
onChange: function(value){
var f = $(this).next().find('input[type=file]')[0];
if (f.files && f.files[0]){
var reader = new FileReader();
reader.onload = function(e){
$('#image1').attr('src', e.target.result);
}
reader.readAsDataURL(f.files[0]);
}
}">
