Show Thumbnail of Image Upload AJAX/PHP


 / Published in: jQuery
 

URL: http://www.jquery4u.com/tutorials/thumbnail-image-upload-ajaxphp/

This is how you can add a file/image upload tool to your forms and have AJAX store the file with PHP and return a thumbnailed version to the user for display on the form. Nice.
