	<h1>Image to sculpting brush converter</h1>
	
	<p>Convert any image to a sculpting brush here!</p>
	<p>
		<strong>Use this channel to convert:</strong>
		<select name="img2brush-channel" id="img2brush-channel">
			<option value="alpha" selected>Alpha (opacity)</option>
			<option value="red">Red</option>
			<option value="green">Green</option>
			<option value="blue">Blue</option>
		</select> 
	</p>
	<p>Only the selected channel is used to determine the weight of the brush - <strong>all other channels are ignored</strong>! Change the channel option <strong>before</strong> you drag + drop the image onto this page.</p>
	<p class="note">Greyscale images are converted to RGB, so <em>red</em>, <em>green</em>, and <em>blue</em> all have the same effect on such images.</p>
