Thread:Extension talk:WYSIWYG/Cannot insert image

I am using MW 1.17.0 and installed wysiwyg-1.6.0_0. I got issues with Image. In image properties window, when I type a image url, the image shows up in the preview box, but it disappears when I click the OK button. I looked into Source and found that the image file name is missing. There is only "" there.
