Image is attached wrongly in CKEditor

If CKEditor is used and an image is inserted to page (selected on local disk and send to server using CKEditor tool), it seems the image is attached in a wrong place, because no image is displayed, only the link to attached image.

The link how it created:

[[image:12923215_10207981763815525_9062058359707412767_n.jpg||height="960" width="720"]]

The link after it's corrected in CKEditor:

[[image:Forums.Pískoviště.WebHome@12923215_10207981763815525_9062058359707412767_n.jpg||height="960" width="720"]]

... so it seems it's not attached to topic page but to forum page.
