When inserting an image in an article using TinyMCE editor's, the popup that appears only has options for Image Source and Alt text but no way to add a title for the image. It seems like there is a way to add this as it is disabled by default according to TinyMCE documentation. I tried changing the /plugins/editors/tinymce/tinymce.php file just to try it out but it does not seem to do anything different in any 'modes'. Is there any way we could enable this or is this not possible?
You can consider change to JCE Editor. This component its great, free and have too many options to manipulate images. Included this your need for title Image. Try In:
