<h4>What is this?</h4>
<p>I found the WordPress Importer plugin is good for importing posts and comments, but is lacking when it comes to importing large attachments (like images) from large sites. My import would often time out and crash. I wrote this plugin to help with my own blog migrations, but I hope you find it useful too.</p>
<h4>Usage</h4>
<ol>
<li>As a prerequisite, import your WXR file using the WordPress importer, but do not select the option to Download and Import Attachments. I have found that an import file up to 15MB big will work as long as you don’t import attachments.</li>
<li>Navigate to the Attachment Importer screen.</li>
<li>Select your WXR export file.</li>
<li>Select the user you would like to be the owner of the downloaded images. Default: current user.</li>
<li>Sit back and let the importer run. The process can take as little as 10 seconds for 10 images, or about two hours for 2000 images. These times depend on the server that hosts your WordPress site.</li>
<li>If you receive any errors during the process, try running the file again after it finishes.  The plugin is programmed to ignore files that match the following criteria:
<ul>
<li>Same name</li>
<li>Same file name</li>
<li>Same upload date</li>
<li>Same file size</li>
</ul>
</li>
</ol>
<h4>How it works.</h4>
<p>This plugin uses <a href="https://developer.mozilla.org/en-US/docs/Web/API/FileReader" rel="nofollow ugc">FileReader</a> and to parse the XML file in the browser, then uses ajax to request WordPress perform individual uploads.</p>

Attachment Importer

Thank you so much for sharing this with the WP community. It helped me get around timeouts and so much frustration. I didn't find any problems with the plugin.

Very helpful plugin that works

I found this plug-in as I was having trouble moving data on a shared server that can not be migrated.
Importing of media that has failed many times is proceeding smoothly.
Thank you for a wonderful plugin !!

Thank you so much!!!!

Even though the plugin hasn't been updated for quite a while, it still works great even with the latest WordPress (5.3). Thanks for the development!

Still great!
