	<h2>RainyShots Plugin Settings</h2>
	<h3>Usage</h3>
	<p>RainyShots adds a template tag — <code>rs_shots()</code> — that returns an array of the recent 15 shots so you can do stuff like this within your templates — </p>
	<blockquote>
		<code>
			$shots = rs_shots();<br />
			<br />
			foreach ($shots as $shot)<br />
			{<br />
			&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;&lt;img src='" . $shot->{&quot;image_teaser_url&quot;} . &quot;' alt='" . $shot->{&quot;title&quot;} . &quot;' /&gt;&quot;;<br />
			}<br />
		</code>
	</blockquote> 
	<p>You can access other properties of each shot in the loop by replacing <code>image_teaser_url</code> with any of the available attributes returned in the JSON as specified by the corresponding <a href="http://dribbble.com/api#get_player_shots">Dribbble API call</a>.</p>
	
	<h3>General Options</h3>
	
	<form name="rsAdmin_form" method="post" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">
		<input type="hidden" name="rsAdmin_hidden" value="Y">
		
		<p><?php _e("ID of Dribbble player*: " ); ?><input type="text" name="rsAdmin_Player" value="<?php echo $rsPlayer; ?>" size="10"><em><?php _e(" ex: rainypixels" ); ?></em></p>
		
		<p><?php _e("Cache Duration (secs): " ); ?><input type="text" name="rsAdmin_CacheDur" value="<?php if ($rsCacheDur != "") echo $rsCacheDur; else echo '86400'; ?>" size="10"><em><?php _e(" ex: 1hr = 3600, 1day = 86400 (default)" ); ?></em></p>
		
		<p class="submit">  
			<input type="submit" name="Submit" value="<?php _e('Update Options', 'rsAdmin_trdom' ) ?>" />  
		</p>
	</form>
	
	<h3>Flush Cache</h3>
	<p>If you'd like to flush the cache, <em>i.e. reset it immediately</em>, click this button —	
	<form name="rsAdmin_form" method="post" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">
		<input type="hidden" name="rsAdminCache_hidden" value="Y">
		<span class="submit"><input type="submit" name="Submit" value="<?php _e('Reset Cache', 'rsAdmin_trdom' ) ?>" /> </span> 
	</form>
