	<h1>Sort Flickr images by tags</h1>
	<p>This simple web application retrieves public images from Flickr that were tagged either as "cat", "dog", or "cow".
	You can copy/move images in different containers according to their tags.</p>
	<p>Following selection modes are supported by default:</p>
	<ul>
		<li>Simple click &mdash; selects a single element, all other elements will be unselected.</li>
		<li>Ctrl+click &mdash; toggles a selection state of an element (use Meta key on Mac).</li>
		<li>Shift+click &mdash; selects a range of element from the previous anchor to the current element.</li>
		<li>Ctrl+Shift+click &mdash; adds a range of element from the previous anchor to the current element (use Meta key on Mac).</li>
	</ul>
	<p>Following drop modes are supported by default:</p>
	<ul>
		<li>Simple drop &mdash; moves elements to the valid target removing them from the source. It can be used to reorganize elements within a single source/target.</li>
		<li>Ctrl+drop &mdash; copies elements to the valid target (use Meta key on Mac).</li>
	</ul>
	<p>Now scroll down and start dragging and dropping, rearrange images using DnD, copy and move them back!</p>
	<p>Status: <span id="status">retrieving a list of Flickr images...</span></p>
