How to upload pictures to jCrop?

I've used the codes I've found from here: http://deepliquid.com/projects/Jcrop/demos.php?demo=thumbnail , but there isn't an upload function. How do I add that?

Like if I use this function how can I implement jCrop?

<form enctype="multipart/form-data" action="save.php" method="POST"> 
<input type="hidden" name="MAX_FILE_SIZE" value="100000" /> 
Choose a file to upload:  <input name="uploadedfile" type="file" /><br /> 
<input type="submit" value="Upload File" /> </form> 

You don't upload images to jCrop, you apply jCrop to your image element.

$(function(){ $('#id_of_your_image_element').Jcrop(); });

replace id_of_your_image_element with the id of your image tag, if you don't have an id on that tag, add one.
