<p>This plugin allows you to tag people and objects in your images by selecting a region of the image and add names, URLs and descriptions.  Implements the jQuery-Notes plugin by Lukas Rydygel (http://jquery-notes.rydygel.de/) and the jQuery-autocomplete plugin by Dylan Verheul (http://code.google.com/p/jquery-autocomplete/).</p>

<h3>Usage</h3>
<h4>Enabling Tags on an Image</h4>
<p>To tag an image, you need to assign the class “wp-tag-people-abc” or “wp-tag-objects-xyz” to your images through your blog’s HTML editor.  ‘abc’ and ‘xyz’ must be unique strings of text to identify an image.  Simply use the ‘Tag People’ or ‘Tag Objects’ buttons found in the editor to easily insert these tags.</p>
<p>To tag people, click the ‘Tag People’ button.  This type of tag allows you to insert names of people and their website or blog URLs.  The URL field may be left empty.</p>
<p>If you wish to tag objects, click the ‘Tag Objects’ button.  This tag allows you to add only textual notes or descriptions.</p>
<p>Some samples:</p>
</p>
<p>If you have more than one image in your post, they must be assigned different classes:</p>
</p>
<p>Do not assign more than one class to an image, such as this:</p>
</p>
<p>Doing so will disable the tagging feature.</p>
<h4>Tagging the Images</h4>
<p>After writing your post, publish it or save it as draft.  View or preview the blog post.  You will notice that each of your images assigned with the required classes are loading tags.  To begin tagging, click the button with the plus (+) sign found below the image.</p>
<p>Click on the image.  Drag and resize the tag box to your desired location and size.  To save the tag, click on the button with the check mark to save it.</p>
<p>To edit or delete a tag, right-click on the tag to make the necessary changes.</p>

Moe Loubani

<p>If you’ve ever wanted to draw on an image or add a caption or text to your image then this is the plugin for you. Best of all it allows you to add your caption, save it, display it, then go back and edit it in different layers and objects laid on top of your image.</p>
<p>It extracts the text from the annotations and displays them as selectable and stylable text just below.</p>
<p>You can hold shift as you draw rectangles to make them perfect squares, same with the ellipse tool and circles.</p>
