<div id="changePic" class="" style="display:none">
                  <form id="cropimage" method="post" enctype="multipart/form-data" action="profile.php">
            <label>Upload your image</label><input type="file" name="photoimg" id="photoimg" />
            <input type="hidden" name="hdn-profile-id" id="hdn-profile-id" value="1" />
            <input type="hidden" name="hdn-x1-axis" id="hdn-x1-axis" value="" />
            <input type="hidden" name="hdn-y1-axis" id="hdn-y1-axis" value="" />
            <input type="hidden" name="hdn-x2-axis" value="" id="hdn-x2-axis" />
            <input type="hidden" name="hdn-y2-axis" value="" id="hdn-y2-axis" />
            <input type="hidden" name="hdn-thumb-width" id="hdn-thumb-width" value="" />
            <input type="hidden" name="hdn-thumb-height" id="hdn-thumb-height" value="" />
            <input type="hidden" name="action" value="" id="action" />
            <input type="hidden" name="image_name" value="" id="image_name" />
            
            <div id='preview-avatar-profile'>
          </div>
          <div id="thumbs" style="padding:5px; width:600"></div>
          </form>
              <div class="modal-footer">
                  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                  <button type="button" id="btn-crop" class="btn btn-primary">Crop & Save</button>

jQuery('#change-pic').live('click', function(e){

     jQuery('#changePic').show();
     jQuery('#change-pic').hide();
    
  });

jQuery("#preview-avatar-profile").html('');
jQuery("#preview-avatar-profile").html('Uploading....');
jQuery("#cropimage").ajaxForm(
{
target: '#preview-avatar-profile',
success:    function() { 
        jQuery('img#photo').imgAreaSelect({
        aspectRatio: '1:1',
        onSelectEnd: getSizes,
    });
    }
}).submit();

    saveCropImage(params);
  });
  //make ajax request to PHP for save image
function saveCropImage(params) {
    jQuery.ajax({
        url: siteurl + params['targetUrl'],
        cache: false,
        dataType: "html",
        data: {

        type: 'Post',
       // async:false,
        success: function (response) {
        jQuery('#changePic').hide();
          jQuery('#change-pic').show();
        jQuery(".imgareaselect-border1,.imgareaselect-border2,.imgareaselect-border3,.imgareaselect-border4,.imgareaselect-border2,.imgareaselect-outer").css('display', 'none');
        
        jQuery("#avatar-edit-img").attr('src', response);
        jQuery("#preview-avatar-profile").html('');
        jQuery("#photoimg").val('');
        AlertManager.showNotification('Image cropped!', 'Click Save Profile button to save image.', 'success');
        
        
        },
        error: function (xhr, ajaxOptions, thrownError) {
            alert('status Code:' + xhr.status + 'Error Message :' + thrownError);
        }
    });
  }
