TinyMCE image

In tinymce, how to replace the button function "insert image" by choose file/upload instead of the actual image URL.

On an other site, I have this system of uploading image from computer.

Thank you. I have already installed it. But there is errors.

- error :   path isn't a directory

-- confirm overwrite : The "xxxxx.jpg" file/directory already exists. Are you sure you want to overwrite this file?

- error : Method importFrom not implemented.

By the way I am looking for an easier image uploader. The simple one of tinyMCE that just ask to choose the file and then upload it.*Because my members can't know how to create folders and so on...

Thank in advance for the help !

 Using a computer does require certain minimal skills. Rather than try to come up with a system that even the dumbest person on earth can use, why not spend some time creating tutorials that show people how to do things. Moxiemanager is probably the best and most intuitive image uploader for TinyMCE there is.  Why sacrifice this in an attempt to make a site that even a retarded goat could use?
