Problems with the Gallery

I can’t get a gallery to appear an actual post. I am using the latest version of WordPress (dashboard reports it as 2.8.4). I just tried to create a gallery in a post for the first time. I clicked “new post”, typed in a title and a few words of text, then clicked “save daft”. I got a permalink assigned (http://ximtc.net/blog/archives/206) and then I clicked the little box for “add an image” next to “Insert/Upload”. I browsed to my sample images folder, CTL-clicked several images, and clicked okay. They all seemed to upload fine, and a new tab, “Gallery (15)”, appeared. I clicked this and saw thumbnails and names for all the images. At the bottom I selected “Attachment pages”, “Title”, “Ascending” and “3” for the respective options, and then clicked “Insert Gallery”. A big yellow box appeared in my post window. Finally I clicked Publish and it seemed to be fine.

Now, however, after following the link to view the post, the title and text appear, but no images. Any ideas?
