I was asked by a new customer to move their WordPress blog to a hosted solution from WordPress.com. After exporting the blog to their XML format, I thought I would have to manually download all 499 images and link them.
WordPress, fortunately, is a little cleverer than that. A simple “Would you like to import attachments?” question during the import of the XML file sorted that out.
Oh, and by the way, if you haven’t already, make sure you’re running the latest version (2.8.4) of WordPress. There’s a nasty exploit going around.
