Automatically creates a sequentially numbered post title of your choosing if the title is left blank when the post is published. The plugin keeps track of what number to use and increments the number every time you publish a post with a blank title. Additionally, the post slug/url will be updated to reflect the new title if the author did not specify one manually.
An options page is available to set the title you want to use or to tweak the incremental number, should it become necessary. This plugin is very basic and is not multi-user aware. If any author on the site publishes a post with a blank title, SequenTitle will do it’s song and dance.

SequenTitle

Automagically set a sequentially numbered post title if you're too lazy to remember what number you're up to.

This plugin behaves similarly to <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">Regenerate Thumbnails</a> except that images are resized automatically / on the fly, when they are used. Once created, they won’t be processed again.
Your thumbnails will now resize when:
<ul>
<li>Image Sizes in Settings > Media is modified,</li>
<li>Switching themes & plugins with different thumbnail / featured image sizes</li>
</ul>
No settings pages, just install and activate and things should work right away.

<h4>What are you talking about?</h4>
Test it out. In your normal WordPress website set up, create a gallery using the Add Media button while editing a post or page and use thumbnails. Afterwards, check out your gallery.
Notice the size of your thumbnails, most likely they’re 150 x 150. Do you see it? Great.
Now head over to Settings > Media and change your thumbnail size to something cooler, something rectangular, let’s try 400 x 200. Save it.
Go back to your gallery that you previously created and refresh your browser. Most likely you won’t be seeing 400 x 200 thumbnails there.
OTF Regenerate Thumbnails fixes this for you.
<h4>Usage</h4>
OTF Regenerate Thumbnails should work right away, and your images should get resized when the dimensions get changed.
For developers & tinkerers, ensuring your images get resized properly requires you to use WordPress’ image functions to display featured images and image attachments. Don’t worry, this is a good thing.
Make sure you use these WordPress functions every time you display images:
<ul>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src" rel="nofollow ugc"><code>wp_get_attachment_image_src</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_get_attachment_image" rel="nofollow ugc"><code>wp_get_attachment_image</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/the_post_thumbnail" rel="nofollow ugc"><code>the_post_thumbnail</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/get_the_post_thumbnail" rel="nofollow ugc"><code>get_the_post_thumbnail</code></a></li>
</ul>
You can also add size names using <a href="https://codex.wordpress.org/Function_Reference/add_image_size" rel="nofollow ugc"><code>add_image_size</code></a>
<h4>Features</h4>
<ul>
<li>Creates Resizes thumbnails on the fly</li>
<li>Handles Image Size settings changes in Settings > Media</li>
<li>Handles thumbnail / image size changes introduced by switching themes & plugins</li>
<li>Works automatically, no setup needed</li>
<li>All calls to <code>the_post_thumbnail</code> and other thumbnail functions are handled automatically</li>
<li>Handles image sizes created from <code>add_image_size</code>,</li>
<li>Handles <a href="https://codex.wordpress.org/Function_Reference/the_post_thumbnail" rel="nofollow ugc">2-item array sizes</a></li>
</ul>
