HTML Editor Insert Image Default Folder

We are using a field named ‘email_message’ and make it 'Use HTML Editor’and in which we use Insert image, which lead us to our server or local upload.we want to make it default folder named ‘brochures’ of our web server.How can we do that.

You may Google “ckeditor default upload folder”

If you can upload, you may have enabled the FileManager extension. If so, the FileManager extension has an advanced setting named “UserFilesPath”. From the notes of the extension:
“UserFilesPath” is a folder under the global upload folder (under PHP → General Options → File Upload tab, see PHP Settings in the help file), e.g. if the global upload folder is “uploads/” (relative to project folder) and “UserFilesPath” is “userfiles”, then the user file folder is “uploads/userfiles” (relative to project folder). If “UserFilesPath” not specified, the global upload folder will be used. Make sure you have setup write permssions for the upload folder properly.

Not sure if this is possible in ckeditor. This is certainly the issue related to ckeditor. If not possible with ckeditor, you will need to find some other html editor for your project. In that case, remove tickmark for Use HTML for your field. Add custom id or class to it and then initialize the new html editor with JavaScript in custom field rendering.
