I’m having the same problem – it doesn’t matter how I type my image tag – the image isn’t showing up in the entry. I look at the source code for the post, and it doesn’t even exist, even though it’s there when I go into the admin panel to edit.
I’ve used the link that the Upload Manager gave me, I’ve taken out the semi-colon, I’ve tried single quotes, double quotes, I’ve tried putting in the entire URL to the image, I’ve used the img quicktag, and I’ve written it by hand, and I’ve brought up the image alone in a browser to make sure it works. I’ve even tried to show images posted on other sites, and I can’t get an image to show up – except on the main page.
The photo shows up on the main page here, but if you look at the first two entries in the archives (Jan 7 and 14) there is no image there, and not even an image tag.

I’d like to use this for the Photo Friday Challenge, but if I can’t post photos in my entries, then it’s useless.
