php - 裁剪后的图片如何上传？

Question

我正在使用java脚本裁剪全尺寸图像并制作缩略图。一切都很好，但我想知道如何在编辑后上传裁剪后的缩略图？有办法上传吗？

我的代码 -当点击“编辑缩略图”时，我们可以裁剪全尺寸图像，当裁剪其在 预览图像 区域中可见时 - 裁剪全尺寸图像后，我们可以单击“应用更改” - 当单击该按钮时 Java 脚本功能激活 -单击时

   var lassoEnd = function() {
              $('thumbnail-controller').innerHTML = "<div><img class='loading_icon' src='public/loading.gif'/>Loading...</div>";
              lassoCrop.destroy();

            I WANT TO UPLOAD MY CROPPED AND CREATED THUMBNAIL IMAGE HERE !

            }

在该功能中，我想上传我创建的缩略图..请帮助我!

 <div id="preview-thumbnail" class="preview-thumbnail">
    <img src="<?php echo $thumb ?>" alt="" id="previewimage" class="thumb_icon item_photo_user  thumb_icon" />  </div>
  <div id="thumbnail-controller" class="thumbnail-controller">
    <a href="javascript:void(0);" onclick="lassoStart();">Edit Thumbnail</a>  </div>




<script type="text/javascript">
        var orginalThumbSrc;
        var originalSize;
        var loader = new Element('img',{ src:'public/loading.gif'});
        var lassoCrop;

        var lassoSetCoords = function(coords)
        {
          var delta = (coords.w - 48) / coords.w;

          $('coordinates').value =
            coords.x + ':' + coords.y + ':' + coords.w + ':' + coords.h;

          $('previewimage').setStyles({
            top : -( coords.y - (coords.y * delta) ),
            left : -( coords.x - (coords.x * delta) ),

            width : ( originalSize.x - (originalSize.x * delta) )
          });
        }

        var lassoStart = function()
        {
          if( !orginalThumbSrc ) orginalThumbSrc = $('previewimage').src;
          originalSize = $("lassoImg").getSize();

更简单的方法是上传裁剪坐标并在服务器端进行裁剪。
