CKEditor missing image source file address?

I novice, with the thinkphp framework to develop a portal site, need to have an article editing function in the background, I use the ckeditor+ckfinder with the ability to upload images, now the issue is the upload icon out, but each time the upload of the prompt missing image source file address.
I would like to ask you a good master what is the cause of this?
Do not know if it will be the path of the problem, by the way attached a few pictures, the first is the view file load CKEditor Place, the second is ckeditor associated Ckfinder place.

Or there are other useful editors can also recommend, thanks!
