SendToEditor image alignment?

Hi

I’ve helped my girlfriend to set up a blog. Everything seems to work just fine, but when sendtoeditor() is being used, the placement of the images are strange.

Hard to explain, the easiest is to look at the post: http://modeblogg.adnic.com/
(see the images at the first post)
If I type for example:

TEST [enter] [insert image]

then I want the image to be placed below the TEST text, but as it is now, the image is being placed to the right of the text.

How do I solve this?
