Uploading images with Windows Live Writer to WordPress

I’ve gone completely insane the last days trying to publish to my WordPress blog (self-hosted) using Windows Live Writer. Most of the time it works, but sometimes it doesn’t (I get Xml-Rpc errors), and I can’t find any clear pattern. Longer posts tend to have more problems than shorter ones, and posts with more images tend to have more problem than posts with fewer images, but sometimes a one line post with one image will fail.

The best workaround I’ve found right now is to upload all images to an FTP directory, instead of putting them in the normal wp-content directory. In Writer that’s Tools, Accounts, Images, Edit…, Images, Transfer images to an FTP server (I’m guessing about the exact labels, since I’m using a swedish copy of Writer, but it should be something like that). Since I made that change, everything has been working, but I’m not ready to count my chickens quite yet…
