It’s a tiny bit more flexible than wp native gallery. It finally allows non-linked images and images linking to external URLs. It also allows linked images/pages opening in a new page.
<h3>Usage</h3>
As it is a shortcode:
^ From the admin wp page->Posts/Pages->Add New or Edit, select HTML in the entry form and enter [galleryjb] 
^ Attach one or more images to the post or define a PostID attribute which has attachements i.e. [galleryjb postid=123] 
^ There are no mandatory attributes: it will show the attached images as a gallery if attachments are present in the current post or in postid, if postid as attribute is defined. 
^ Optional attributes are all those you can see in wp 3.0.4 or 3.1 of native gallery plus: 
^^ link: besides “file” (= images are linked to imagefile) and the default null string (= images are linked to the attachment’s permalink) already present in wp gallery, there is now “null” (images are not clickable/linkable) and “url” (images are linked to external URLs defined in Description). 
Please note that if you choose link=”url”?, the Description textbox in Media library needs to contain a url (http(s)..etc) and not a textual description. On the other hand, Description is not used by wp native [ gallery ] in any case. 
^^ target: boolean. if true linked objects open in a new/the same window, if false (default) in the same window 
^^ author: true (default) or false whether you allow this plugin’s author footer to be displayed or not (please, say yes).
<h3>Examples</h3>
[galleryjb link=”null”?] ==> Images are not clickable 
[galleryjb target=”true”?] ==> Images link to the attachment’s permalink and open up in a new page 
[galleryjb link=”url”?target=”true”?] ==> Images link to external URL defined in the Description textbox (in Media library). These URLs will open up in a new page. 
[galleryjb link=”url”?] ==> Images link to external urls defined in the Description textbox (in Media library). They will open up in the same page (as default)

Leadwhite Mosaic Gallery for Elementor adds a Tiled Gallery widget to Elementor that produces a varied mosaic layout driven by image aspect ratios — similar to Jetpack’s Tiled Mosaic gallery but built natively for Elementor with full style controls.
How it works
Images are grouped into rows automatically based on their aspect ratios. Each row uses the best available shape from a library of eight layout patterns (adapted from Jetpack’s open-source grouper):
<ul>
<li>Symmetric Row — portrait, two stacked landscapes, portrait</li>
<li>One Three — portrait + three stacked landscapes</li>
<li>Three One — three stacked landscapes + portrait</li>
<li>One Two — single + stack of two</li>
<li>Two One — stack of two + single</li>
<li>Four — four singles</li>
<li>Three — three singles</li>
<li>Panoramic — single wide image fills the row</li>
</ul>
Row heights and column widths are calculated from aspect ratios so all images in a row share the same height, with no cropping distortion.
Features
<ul>
<li>Tiled mosaic layout with 8 shape types</li>
<li>Hover overlay with background colour, fade or slide-up animation</li>
<li>Title and description pulled from attachment metadata (title, caption, alt, description)</li>
<li>Independent typography controls for title and description</li>
<li>Image border, border radius, and CSS filters (Normal and Hover states)</li>
<li>Zoom In hover animation on images</li>
<li>Responsive — stacks to single column below a configurable breakpoint</li>
<li>Elementor lightbox integration</li>
<li>Assets load only on pages where the widget is used</li>
</ul>
<h3>Usage</h3>
<ol>
<li>Add the Tiled Gallery widget to any Elementor page</li>
<li>Add images via the Gallery Images control in the Content tab</li>
<li>Configure layout (gap, mobile breakpoint) and interaction (lightbox, link) in the Content tab</li>
<li>Set overlay and image styles in the Style tab</li>
<li>Add captions or titles to images in the WordPress Media Library — these are used by the overlay Title and Description controls</li>
</ol>
