Add a template to NextGEN Gallery that provides multiple-file downloads for trade/media galleries. <a href="https://wordpress.org/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a> is one of the best gallery plugins for WordPress because it is very flexible and has a nice, simple admin. This plugin adds a new gallery template that lets you select multiple images from the gallery to be downloaded as a ZIP archive.
NB: the Photocrati version of NextGEN Gallery can impact the performance of your server, and not all of the old plugin’s functionality works. You might want to consider using <a href="https://wordpress.org/plugins/nextcellent-gallery-nextgen-legacy/" rel="ugc">NextCellent Gallery</a> instead — it’s a fork of the original NextGEN Gallery with continued support and compatibility, without the performance impacts.
NextGEN Download Gallery is targetted at creating “Trade/Media” areas on websites, allowing journalists to easily download multiple product images. It’s apparently very popular with photographers too.

This program incorporates a little code that is copyright by Photocrati Media 2012 under the GPLv2. Some PHP code was copied from NextGEN Gallery and altered, so that the <code>nggtags</code> shortcode could be extended as <code>nggtags_ext</code> and specify a gallery template.

<a href="https://wordpress.org/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a> (NGG) is an excellent gallery for WordPress. Its major drawback, as far as I’m concerned, is the minimalistic image chooser. So I’ve taken the liberty to adapt the equally excellent <a href="http://g2image.steffensenfamily.com/" rel="nofollow ugc">g2image</a> image chooser, which also is embedded in the WPG2 connector to Gallery2.
This image chooser allows to browse through hierarchical albums and galleries, insert NGG tags for albums and galleries, as well as NGG and HTML tags for one or more images and thumbnails at a time.
<ul>
<li>On the left side of the image chooser pop-up there is the tree view of all albums and galleries. On the top are the albums and their galleries, then follow the galleries, which are not attached to any album.</li>
<li>On the upper right side there are the controls to insert the tags with their relevant options. Depending on which insert mode (NGG or HTML tag, image or thumbnail) is selected, only the relevant options are shown.</li>
<li>Below the controls, the thumbnails of the images in the selected gallery are shown, optionally together with their title, summary and description. There multiple images can be selected for insertion. </li>
</ul>
At present, the NGG tags [album], [nggallery], [thumb], [singlepic], and [imagebrowser], plus some html links are supported.
Default settings can be altered on the settings page.
NOTE: This plugin does not work with the new Gutenberg editor. There now is a new plugin that allows you to insert NGG tags for images, galleries and albums as Gutenberg blocks: <a href="https://de.wordpress.org/plugins/ngg-image-chooser-block/" rel="nofollow ugc">Image Chooser Block for NextGEN Gallery</a>. 
Alternatively you can switch to the classic editor, e.g. by using the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> plugin.
At this time, the image chooser is available in English (default) and German. Other translations are welcome and will be included in the next release.
