Using the following Demo as a sort of Guide, you can make this work better:

http://jqueryui.com/droppable/#photo-manager

With the idea that the user would want to upload an image and then place it on the shirt, I created an upload preview first. This can then be dragged onto the target shirt. It then needs to be appended to #boxes, allowed to be dragged, and resized.

Here is my working example: https://jsfiddle.net/Twisty/4ezggt9h/

HTML

<div class="work-wrapper">
  <div id="firstshirt" class="container">
    <div id="boxes" class="container">
      <img id="img-1" src="https://torcdesign.com/shirts/brown.jpg" />
    </div>
  </div>
  <div class="control-wrapper">
    <h3>Controls</h3>
    <a id="btn-Preview-Image" class="button">Preview</a>
    <a id="download" download="my_image.png" class="button disabled" href="#">Download Image</a>
    <select id="imajes45">
      <option value="">Choose Source</option>
      <option value="new-upload">Upload Images</option>
      <option value="select-item">Select Item</option>
    </select>
    <div class="file-upload-wrapper" id="draggableHelper" style="display: none;">
      <input type="file" class="upload-img" name="file1" id="upload-img-1" />
      <div id="upload-preview" class="small upPreview">
        <span>0/3</span>
        <ul id="preview-gallery" class="gallery ui-helper-reset ui-helper-clearfix">
        </ul>
      </div>
    </div>
    <select name="subselector" class="file-select" style="display: none;">
      <option value="">Choose Gallery</option>
      <option value="bulldog">Bulldogs</option>
    </select>
    <div id="bulldog-gallery" class="upPreview hidden">
      <ul class="gallery ui-helper-reset ui-helper-clearfix">
        <li class="ui-widget-content ui-corner-all"><img src="https://torcdesign.com/clipart/pT78gE6pc.gif" class="icon" /></li>
        <li class="ui-widget-content ui-corner-all"><img src="https://torcdesign.com/clipart/LiKkRqkeT.gif" class="icon" /></li>
      </ul>
    </div>
  </div>
</div>
<h3>Result:</h3>

  <div id="previewImage"></div>
