Image Alt Sync scans selected posts and updates any <code><img></code> tags found in the post content that reference media items (class <code>wp-image-###</code>), and replaces their <code>alt</code> attributes with the attachment’s <code>_wp_attachment_image_alt</code> value: 
– If the image is in the Media Library, it prefers the attachment’s Alt Text. 
– If no attachment alt is set, it falls back to the image filename (without extension) or the post title (configurable in the UI). 
– Optionally skip images that aren’t found in the Media Library. 
– Optionally restrict by image file extensions (e.g. <code>jpg,webp</code>).
Run in dry run first to see exactly what would change. The log shows each post processed and any per-image alt changes.
Highlights 
– Processes per post in batches with a customizable delay (default 100 posts, 1s). 
– Filter by post status and date range (quick buttons: Today, Yesterday, Last week, Last month, YTD, All). 
– Validate that “Date after” ≤ “Date before”. 
– Limit by Post ID range with buttons to auto-fill lowest and highest post IDs. 
– Skip posts without <code><img></code> (optional). 
– Exclude image extensions (comma-separated, e.g. <code>.svg,.gif</code>). 
– Dry run (browser & WP-CLI) shows clickable post IDs, post titles, filenames, and detailed old → new alt replacements. 
– Only processes posts that have at least one image attachment.

<h3>Usage</h3>
<ol>
<li>Choose your filters (date range, min/max post ID, or “Apply to all posts”).</li>
<li>Set Batch size and optional Delay between batches to throttle load.</li>
<li>Choose a Date Range, or click a shortcut button (autofills Date after/Date before).</li>
<li>(Optional) Enter Lowest/Highest Post ID or click the quick-fill buttons.</li>
<li>(Optional) Check Skip posts without <code><img></code>.</li>
<li>(Optional) Enter Exclude extensions like <code>.svg,.gif</code>.</li>
<li>Optionally enable Dry run to preview changes without saving.</li>
<li>Click Start. Progress and detailed per-post changes appear in the log.</li>
<li>If needed, click Stop to pause after the current batch finishes.</li>
</ol>
Tips 
– Use the “Lowest ID” and “Highest ID” buttons to auto-fill the ID range. 
– Use the extension filter (e.g. <code>jpg, jpeg, png, webp</code>) to target specific image types. 
– Check “Skip images not in media library” to avoid external or missing files.

Upload Unziper let’s you upload zip-archives and have them extracted, each file properly attached to the current post.
It’s built upon and meant to replace James Revillini’s now-broken <a href="http://james.revillini.com/projects/just-unzip/" rel="nofollow ugc">just-unzip</a>, and expands on the original plugin in the following ways:
<ul>
<li>runs all files through WP’s sanitize filter to ensure valid filenames</li>
<li>does not attach duplicates</li>
<li>does not replace files with the same name</li>
<li>correctly deals with nestled directories </li>
<li>uses the latest WP core functionality and the latest PclZip version</li>
<li>and – perhaps most importantly – it works! 😉</li>
</ul>
In short – it’s a nice way to do batch uploading. I highly recommend you combine it with an <a href="https://wordpress.org/extend/plugins/mini-slides/" rel="ugc">inline image viewer</a> and a plugin to better <a href="https://wordpress.org/extend/plugins/custom-upload-dir/" rel="ugc">organize your uploads</a>.
<h3>TODO (help needed)</h3>
This plugin could do with a few options. As it is, it’ll always unzip archives and then delete them – which might not always be desired.
There are options for this already used in the plugin so it shouldn’t be a problem, but I just loath front-end development. Placing a few tickboxes in the ‘upload’-iframe would do the trick. If you’ve got a few minutes to throw something together, please email me or post a comment to this plugin.
Options I’d like exposed:
<ul>
<li>delete zip when done (default: true)</li>
<li>unzip and attach (default: true)</li>
<li>attach zip to post (default: false)Copyright (C) 2007 Ulf Benjaminsson (ulf at ulfben dot com).</li>
