I am working on implementing TinyMCE editor for textarea , as a callout. (I received some partial code implementation, and I have to configure/modify it for one project).A custom IPL file renders the TinyMce editor. A custom file browser is also implemented. In the Tiny editor when the button for Insert Image is clicked, an html page pops up. This page is part of the advimage plugin, the location/name of the html file is: /tinymce/jscripts/tiny_mce/plugins/advimage/image.htm. This HTML is part of the advimage plugin package and it is not modified by me."image.htm" contains fields for image path and its properties. There are two more fields for mouseover and mouseout images paths as well. "image.htm" has a button for invoking the custom file browser. The custom file browser can correctly transfer the image paths (main image as well as mouseover/out) to "image.htm". When the "insert" button is clicked in "image.htm" , the expected behavior is to see all the selected images as well as their properties to the TinyMce editor. The main image and its properties are correctly transferred to Tiny Editor. But the mouseover/out image paths are not transfered to TinyMce editor . Here is the sample content copied from "image.htm" to TinyEditor.<img hspace="10" height="96" width="175" vspace="10" border="4" src="/images/safari.jpg" alt="Image Description" title="Image Title" />Question:1) How can the mouseover/out fields be copied from "image.htm" to the TinyEditor? Is there any special configuration for this? I do not see anything special written in the custom code that copies the main image and its properties (this already works correctly) and I believe that TinyMCE javascript is taking care of this. 2) Can we control what fields show up in "image.html" through some configuration ?
