- You can download the script from this link: CKEditor Image Upload.

• To test the script: Demo
For comments, questions, or any issue related to this addon, write on Forum, in the "Scripts from Website" category.


1. To use this addon in CKEditor, Download the script and copy the "imgupload.php" file in the "ckeditor/plugins/" folder. Or, copy the code bellow, and add it into an "imgupload.php" file in "ckeditor/plugins/" folder.
2. Change the value of $upload_dir variable (line 5), with the path of images-directory on your server, RELATIVE TO THE ROOT OF YOUR WEBSITE ON SERVER.
3. By default, if the uploaded file name exists on server, it will be renamed with "filename_NR.ext" (NR is a number). If you want to Overwrite the existing file, set value of 0 to RENAME_F (line 9).
4. Sets CHMOD writable permision (0777) to image-upload folder on your server (if on Linux system), to allow PHP to upload the files.
5. Enable the plugin by adding the filebrowserImageUploadUrl parameter in CKEditor configuration on your page:
CKEDITOR.replace('textareaId', {
 "filebrowserImageUploadUrl": "/path_to/ckeditor/plugins/imgupload.php"
