Gallery plugin that’s simple because it leans on existing WordPress gallery features provided by http://sethmatics.com/.
NEW TO WORDPRESS? Please read about how the default gallery works at https://codex.wordpress.org/Gallery_Shortcode
We decided that the default gallery that WordPress builds is lacking some very simple features. 
Enhance your gallery’s without having to learn a completely new interface! Upload images as you 
normally would, insert the “gallery” tag as you normally would, with the plugin enabled BAAM! 
Your gallery is not in a beautiful showcase. Wait, don’t have room on your page for a showcase? 
No problem, we got you covered! Ad a simple attribute (modal) to the gallery code and define a 
thumbnail image… now you have a thumbnail that opens an overlay box on the page with your gallery showcase 
in it. No, it doesn’t navigate away from the current page, its very similar to a lightbox effect.
But wait, you want more you say? Oh you mean you use the featured image enhancement from WordPress? 
Good news, we even offer you the ability to link your featured image to your gallery showcase. It 
will cause the featured image, when clicked, to open the sexy overlay box for you. Snazzy!
Great…. so now I have to worry about 10 more javascript libraries on my page… Nope! The only 
scripts we are loading on the page are jQuery UI and small gallery plugin for jQuery. This means it 
shouldn’t conflict with any of your other site features. Well, if your not sold yet, just try it out 
and see for yourself how quick and easy it is to extend the gallery WordPress features.
Features include:
<ul>
<li>uses the existing WordPress gallery shortcode to keep inserting galleries easy and simple</li>
<li>tiny plugin, overhead media files and scripts are minimal</li>
<li>scripts optimized to be loaded at proper times to keep page load time down</li>
<li>extends featured images to link them to a gallery of your choosing</li>
<li>built as part of the SM plugins group which is being compiled to optimize page load speeds when using SM plugins together by minimizing files loaded on the site to 1 library. Stop loading 50 stylesheets and 39 javascript files, instead using the SM Plugins will pull from a single library and detect whats been loaded to keep you site load time down.</li>
</ul>
Features Coming in version 2, Next Version Updates:
<ul>
<li>javascript post-load images upon visibility to reduce page load time</li>
<li>modal box will load its contents with AJAX to reduce page load time even more</li>
<li>some styling options inside the wordpress interface (currently only available using CSS)</li>
<li>ability to select more plugin options while inserting the gallery from the WordPress media popup</li>
<li>ability to select an existing image from the media gallery for use as a gallery thumbnail image</li>
</ul>
Don’t forget to rate our plugin so we know how we are doing!

SM Gallery

WordPress themes need thumbnails in different sizes and they even let the user to change those dimensions. 
But WordPress has a problem: it does not regenerates the thumbnails when new sizes are registered.
Thumbnails intercepts the request by themes or plugins to WordPress to get a specific thumbnail, generates it and caches it on disk. 
Efficiently, it produces a perfectly cropped image, with the right dimension avoiding unpleasant stretching.
Thumbnails does not modify your blog or your media library. When deactivated the blog returns to its old behavior.
The second important feature is the autoselection of featured image for post which are missing it. 
You can choose between the on the fly selection without persist it or, for better performances, to persist it once selected.
Read the <a href="https://www.satollo.net/plugins/thumbnails" rel="nofollow ugc">Thumbnails</a> official page for detailed information.
Theme developers can find instructions to use it (no code tied to Thumbnails needs to be written!).

Thumbnails and Featured Images

This plugin solves my problems with the WP thumbnails, thanks Stefano!

The one that solves my problem

I re-use my post thumbnail images in various ways, so I like to upload them full size, and I need the software to resize them as needed. This plugin does exactly that for me.

It performs its magic transparently and makes my pages a lot lighter. Highly recommended.


Amazing

I like this plugin's approach of generating thumbnails when asked.
I hope the plugin will be around for a long time.
Or if it were included in the core, it would cut down on wasted unused image files on servers around the world.

Now if only it would support WebP and responsive images, it would be perfect.

Thanks.

should be included in the core.

Autoselect the featured image and creates pixel perfect resizes on the fly without regenerate all the thumbnails.
