Faster Image Insert aims to do one thing right:
Moves built-in Media Manager down in a meta-box, right next to main editing panel, so you have full control of the manager: opens it, makes it collapse or hidden from the interface completely.
Best of all, is now you can insert image(s) much faster, and precisely where you want them to be.
<ul>
<li>No thickbox, using metabox with zero interface blocking, quite similar to the uploader in WordPress 1.5</li>
<li>No hacking, default upload interface is not affected, only enhanced.</li>
<li>Insert multiple images in gallery & library mode, without using shortcode; can also insert images in reversed order, and even control spacing between images.</li>
<li>Mass info editing, change title/captions in one-shot.</li>
<li>Smart switches: set default uploader, disable captions.</li>
</ul>
This plugin is designed for:
<ul>
<li>Screenshot lover – movie, game or anime review etc.</li>
<li>Howto guru – cooking guide, hardware DIY guide etc.</li>
<li>Photo logger – author can comment below each photo.</li>
<li>Blogger that has been shouting “run, thickbox, RUN!” to the loading screens.</li>
</ul>

This plugin gives the capability to automatically add content before and/or after your posts, pages, or any public custom post types.
It is also possible to prevent your before/after content from showing on a post or a page directly from the editor screen (works on both Classic Editor and Block Editor). You can also prevent your before/after content from displaying on specific post types or categories.
With this plugin, build your before/after content within the Gutenberg block editor, even if you are using Classic Editor!
Indeed, the block editor is activated for these specific blocks of contents even if Gutenberg is not activated on your website!
I strongly recommend to use it alongside one of my other free plugins, <a href="https://wordpress.org/plugins/reusable-blocks-extended/" rel="ugc">Reusable Blocks Extended</a>. These two plugins are totaly independant, but together they provide a full editorial experience! ⭐️

Insert Blocks Before or After Posts Content

The Blocksy theme gives the opportunity to customize some features before and after the content but prevent you to choose the order of eventual additional content you may try to add in these places. This plugin is pretty cool as you can add all the blocks you need in the order and composition you need.

Very handy

Automatically insert blocks of content before and/or after each posts/page content.
