=== Import External Images 2 v2.0.6 ===

Makes local copies of all externally linked images and (Optionally) PDFs in a post or page.

== Description ==

Imports remotely hosted images and PDFs where they are referenced within a post and updates their links to point to the local file.

The plugin shows a number next to the title of posts that contain external images. This number includes the count of links to external images that can be updated. Consider this number to be a count of total changes to be made i.e. it includes images to be imported and links to be updated.

= Features =

  • Import externally hosted images
  • Import post-by-post during post editing
  • Import to multiple posts at a time by visiting Dashboard > Media > Import Images

= Credits =

Version 1.5.x and above: Released by VR51.

This plugin is based on Import External Images by Marty Thornley https://github.com/MartyThornley/import-external-images, which is based on the "Add Linked Images to Gallery" plugin by http://www.bbqiguana.com/.

== Installation ==

  1. Download the "Import External Images 2" zip file.
  2. Upload to your WordPress plugins directory.
  3. Activate the plugin via the WordPress Plugins tab.
  4. Navigate to Media > Import Images or edit a post to import externally linked media.

== Frequently Asked Questions ==

= How does this plugin work? =

This plugin will find IMG attachments or PDF attachments within posts and pages. Any external attachments will be downloaded to your site's media library and their links in posts/pages will be changed to those of the file in your own website's media library.

= Does it work with MultiSite? =

Yes!

= What if I don't want to import images from a third party image hosting site? =

You can use the settings page to make Import External Images 2 ignore domains.

= Images won't import. What can I do? =

  • Install (WP Sweep)[https://en-gb.wordpress.org/plugins/wp-sweep/] Visit Tools > Sweep then sweep the transients (it is the bottom option).
  • Confirm the server that hosts the images does not use hotlink protection. If images are protected you won't be able to download them in some cases.
  • Make sure the site that hosts the remote images is not in maintenance mode and is not blocking your own site's IP address.

= I can't use the bulk image importer to import images into multiple pages simulataneously. What gives? =

This bug began with the release of WordPress 4.9.1 and vanished with 4.9.3. Hopefully you will not meet this bug.

Sometimes pages need to be visited by the admin user before images will import. The pages only need to be briefly opened then closed in a browser tab in the same browser as your active admin session or in a different browser on the same machine (i.e. you don't need to be logged in when viewing the pages).

Use the site's sitemap to visit pages or use the 'view' button next to each post in the bulk options page then run the importer again.
