30	<h2 class="photonic-section">What is the <code>gallery</code> shortcode?</h2>
31	<p>
32	The <code>gallery</code> shortcode is the backbone of creating galleries in WordPress. By default
33	Photonic
34	uses this and adds on a bunch of goodies to it. If you happen to deactivate Photonic, you wouldn't
35	be dealing with
36	a mess of shortcodes, since the <code>gallery</code> shortcode fails gracefully and without any ugly
37	errors.
38	</p>

40	<h2 class="photonic-section">So why might you want to replace it?</h2>
41	<p>
42	Let's say you have an established website and have made heavy use of Photonic galleries. Then, one
43	fine day,
44	you change themes or add some plugin, which also uses the <code>gallery</code> shortcode. You now
45	have a conflict!
46	This page gives you a very easy way to work around this conflict.
47	</p>
48	<p>
49	In addition, this method also lets you separate your shortcodes, so that in case you decide to
50	switch over the shortcodes
51	to Gutenberg blocks, you would only be targeting Photonic's shortcodes instead of others.
52	</p>
53
54	<h2 class="photonic-section">Alright, let's do it!</h2>
55	<?php
56	global $photonic_alternative_shortcode;

58	?>
59	<p>
60	You have not defined a shortcode to which you can convert. Please do so from <em>Photonic →
61	Settings →
62	Generic Options → Generic settings → Custom Shortcode</em>.

64	<?php
65	}
66	elseif ('gallery' === trim($photonic_alternative_shortcode)) {
67	?>
68	<p>
69	Please use something other than <code>gallery</code> as your custom shortcode. Using <code>photonic</code>
70	is probably a good idea.

72	<?php
