/*
* Inline uploading of images for the Jquery MarkItUp editor.
* @see http://markitup.jaysalvat.com/
*
* The purpose of this is to avoid having to have already uploaded an image (and
* to know the URL) when adding an img tag to edited content. This widget handles
* the upload itself.
*
* The "Picture" button will reveal a dialog from which an image to be uploaded
* is chosen. The upload's form target is a hidden iframe also within the dialog.
* Once the iframe has loaded, the JSON response is parsed and the img tag is built
* and then added to the editor selection.
*
* The server-side script should respond with a JSON object wrapped inside a textarea tag.
* @see http://jquery.malsup.com/form/#file-upload
*
* The JSON object should include the following:
* on success:
* - status: string, 'success'
* - src: string, the complete URL to the image
* - width: string, the image width in pixels
* - height: string, the image height in pixels
*
* on error:
* - msg: string, whatever error msg you want to display
*
* All of the upload form inputs are submitted, so the server-side script might also make use of
* the class or id assigned to the image. For example, if the image information is to be saved to
* a database. In that case, it might also be desirable to have this script create hidden fields
* with further data, like a content ID, so as to better identify the image.
*
* Keep in mind that one might have both this widget and the classic Picture buttons in the same toolbar.
*
* This particular example REQUIRES the jQuery.loading and jQuery.json plugins.
* @see http://code.google.com/p/jquery-loading-plugin/
* @see http://code.google.com/p/jquery-json/
