Hi pallavipatni,
If you ask about change names of files displayed within "Files" of the "Modify image" dialog, then that is not possible. Those files are located on server and end user only may request to show them in editor.
If you ask about the "Upload File" button, which targets the INPUT filled by action of "Browser..." button, then, I guess, changing file name should be possible. The "Browse..." button opens standard windows "upload file" dialog. While browsing through available local files (if it is supported by end user machine), the end user may find a particular file, change its name and "Open" (request to upload) that renamed file.
Thanks for the response.Yes i know the 'Files' displays images from the server only. And you got it right i was asking about the upload image only. Now can you please tell me how to do that? because im not able to find that particular process where that browse button's execution taking place, so that i can change edit that name of the file aftr browsing it.
thanks
