I am in the process of transferring posts from one WordPress install to another. I can use WordPress' Tools --> Export to export the XML I need for my posts. On the new install, I then use Tools --> Import to load the XML. I check "Download and import file attachments" and then finish the import. The pictures that are inline in my post work, but there are no images to be found in the posts' media gallery. The gallery tab under Upload / Insert is nonexistent, meaning there are no attachments associated with the new post.
I currently have the posts migrated, but attachments are still not. How can I do this? And also include the existing captions, descriptions, titles, etc.
Edit: I should add that this was a migration, so the site URL stayed the same -- It it just the server / WordPress install that changed. Therefore the image paths stayed the same, but they pictures just aren't registered in the posts' Media Gallery.
