Weirdness when inserting images

[high2K]

When I try and insert an image into define_main_page.php via Tools> Define pages editor, the insert image facility is looking for it in the wrong directory.

I upload images to the main 'images' directory, but i get an error saying that the image can't be found. The path in the error message is incorrect as the path shown in the insert image window is editors/htmlarea/popups/images/myimage.jpg

Why is it looking there and how do i stop it?
If I type the path into the html code it still can't find the image, unless I type in the full URL [http://blahblah.com]

Weird huh?
