A plugin which adds a shortcode: <code>[gallery_from_regex_matches]</code> in which a regex attribute should be specified. It will then look for matches in the descriptions and titles of all published images in your library, and create a gallery from the matches it finds.
<ul>
<li>Use for example like this <code>[gallery_from_regex_matches regex="lillill" exclude_ids="764"]</code>, and it will generate a gallery of all your pictures of “Lillill”, except the one which has ID 764.</li>
<li>Sometimes it might be advicable to limit the amount of matches. that can be achieved by adding <code>limit</code> to the shortcode. <code>[gallery_from_regex_matches regex="lillill" exclude_ids="764" limit="10"]</code>.</li>
<li>Sometimes you want to make a gallery of “cats” but not “catsup”, but you don’t want to add <a href="https://dev.mysql.com/doc/refman/5.7/en/regexp.html" rel="nofollow ugc">word boundary</a> <code>[[:>:]]</code>, in this case you can <code>exclude_regex=catsup</code>. Then it could look something along the line of <code>[gallery_from_regex_matches regex="cats" exclude_regex="catsup"]</code>.</li>
<li>The same params (except for <code>ids</code>) as for the <code>[media]</code> shortcode can be used (as this plugin calls that shortcodes callback function (<code>gallery_shortcode()</code>) to generate the gallery), so if you want to specify a particular type (style) of gallery from for example your cat pictures , this might do the trick: <code>[gallery_from_regex_matches regex="(cat|kitten)" type="square"]</code>.</li>
<li>The regular expressions follows the <a href="https://dev.mysql.com/doc/refman/5.7/en/regexp.html" rel="nofollow ugc">MySQL Regexp syntax</a></li>
<li>Some characters will per default not work inside of the shortcode, see the “Caveats” section.</li>
<li>There are no bells and whistles for this plugin but it could potentionally be added in the futre.</li>
</ul>
<h3>Caveats</h3>
Since the regex used by the plugin is specified as an attribute value inside of a shortcode, and the <a href="https://codex.wordpress.org/Shortcode_API" rel="nofollow ugc">Shortcode Api</a> disallows the use of certain characters which could be a part of a valid, useful regex, there are some things to consider.
<blockquote>
Attribute values must never contain the following characters: 
 * Square braces: [ ] 
 * Quotes: ” ‘
[ … ] 
 The recommended method of escaping special characters in shortcode attributes is HTML encoding. Most importantly, any user input appearing in a shortcode attribute must be escaped or stripped of special characters.
</blockquote>
<ul>
<li>if in the regex you need to macth a character set <code>[a-z]</code>, then (following the shortcode Api documentation guidline), they need to be encoded. There are two encodings which the plugin accepts: “html” and “base64” </li>
<li>Currently there is no way to encode these things with help of the plugin, although it is planned for a future release, so the regexes must be encoded manually for now’ 
For example, for regex <code>w[0u][0u]ti</code> can be expressed either:</li>
</ul>
With HTML encoding: 
 <code>[gallery_from_regex_matches regex="w&#091;0u&#093;&#091;0u&#093;ti" encoding="html"]</code>
With Base64 encoding: 
 <code>[gallery_from_regex_matches regex="d1swdV1bMHVddGk=" encoding="base64"]</code>
To encode a string to base64, it can be done from the terminal like this: 
 <code>% echo -n "catsup" | base64 
Y2F0c3Vw 
% echo -n Y2F0c3Vw | base64 --decode 
catsup%</code>

Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery


We recently had a plugin conflict with Rank Math, but we were able to get a prompt response from support letting us know that our issue has been identified and will be fixed in the following update.


Support is responsive


Great plugin, except for one part.The "Manage Album" page gets really slow with many albums. We have 612 albums and 2491 galleries. And it takes a few minutes to load.But luckily the functions are quite accessible within our own plugin, therefore we don't use the official backend anymore. 



The support is helpful and fast.


Great plugin and easy to customize

The most popular gallery plugin that lets you create galleries and albums in seconds.
