Attachment Importer is a WordPress plugin designed to streamline the import of large media files from WXR export files. While the standard WordPress Importer handles posts and comments well, it often struggles with large attachments, leading to timeouts and crashes. This plugin addresses these issues by allowing users to import images and other attachments efficiently after the initial import of content. Users can select the owner of the images and monitor the import process, which can vary in duration based on the number of files and server performance.

To use Attachment Importer, users must first complete a standard import without attachments, then navigate to the plugin’s interface to select their WXR file. The plugin intelligently skips over files that match certain criteria to prevent duplicates, ensuring a smooth import experience. With features like an overall progress bar and error handling improvements, this tool is a valuable addition for those managing large WordPress sites.
