Is there an extension, or a technique, during Wordpress import to pull in an attachment URL that doesn't have a file extension?
I'm trying to import a Square Space blog into Wordpress. Most of the posts and URLs come over, but there's a small number (eight), where the images can't be imported. The importer fails with a message like
Failed to import Media “attachment-50b1b915e4b01c11f0ef7db4”: Invalid file type
If I lookup the attachment-50b1b915e4b01c11f0ef7db4 attachment in the XML import file, I find the following item node set
<item>

Zooming in on the attachment URL, that's
http://static.squarespace.com/static/50a97ccee4b040d1420f6022/50a97ccee4b040d1420f6032/50b1b915e4b01c11f0ef7db4/1353824560608/file
There's no file extension on this URL. It appears that the wordpress-importer plugin checks the file types of the URL by extension, using the wp_get_mime_types function.
Is there a way to work around this by mapping via the Content/Type header, or manually mapping specific URLs to specific file types during import?
