How to attach files with metaWeblog to a blog post? - metaweblog

Question

I'm trying to post to my blog with images.
Yes, I can upload images and I can see that images in the content of post
but it's not in a attached file list.
How can I put the images that I upload in the attached file list?
When I'm posting with MS word 2010 to my blog, images that I put on the word are always updated in a attached file list. But my php source doesn't.
Is there any way to attach files to a blog post?
