Media

Which attachments are exported

When you export some items (not all content):

1. WordPress adds each item’s attached media (post_parent) and featured image (_thumbnail_id).
2. The plugin also adds the media the items use in their content without being attached: images, galleries, covers, files, video and audio inserted from the library. It finds them by:
   • block attributes: "id" (image, cover, file, video, audio), "mediaId" (media & text), "ids" (gallery);
   • wp-image-<id> classes and the [gallery ids="…"] shortcode;
   • upload URLs, sized ones included (-300x200), through attachment_url_to_postid().
3. Plugins add more with eizport_media_used — the WooCommerce compatibility adds product galleries.

Turn step 2 off with Settings → Export → Only attached media, or per export with media_used: false.

Media files in the bundle

Media files (on by default) puts the files of every exported attachment inside the bundle, under uploads/ with the same folders as on the old site. On import they are served to the importer from the bundle, so nothing is downloaded and the old site can be offline.

Only files in this site’s uploads folder go in; offloaded media (a CDN, S3) is left to the importer to download, as usual.

Example

A page with an attached image (A), a different featured image (B) and an image from the library in its content (C):

Setting	Exported
Default	the page, A, B, C
Only attached media	the page, A, B
