Joomla stripping out #usemap - joomla

Question

I have a map inside a TinyMCE editor in Joomla 3, and it seems like when it is saved Joomla is messing with the html. I just want no filtering or anything.
So this is the HTML I enter:
<img class="mapper noborder"
height="410"
id="Map_of_North_America"
name="Map_of_North_America"
src="/images/State Maps/Map_of_US_web_2014(1).png"
style="border-width: 0px; border-style: solid;"
usemap="#m_Map_of_North_America" width="476" />
and this is what Joomla saves:
<img class="mapper noborder"
src="images/State Maps/Map_of_US_web_2014(1).png"
width="476"
height="410"
name="Map_of_North_America"
style="border-width: 0px; border-style: solid;" />
It removes the id, as well as the usemap=
I have tried setting text-filtering to none, changing up the TinyMCE in the plugin manager etc... Thoughts?

Answer 1

I had the same problem however with JCE (I am not using TinyMCE) bu I guess, this could help :
in JCE / Edit Profile / Features and Layout: at the bottom : check the option "Adds support for OBJECT, EMBED, AUDIO, VIDEO and IFRAME elements. Required by the Media Manager and when inserting Adobe® Flash®, Quicktime® and other media file types"
in JCE / Edit Profile / Editor parameters/advanced : set all to yes
in JCE / Edit Profile / Plugin parameters/media support : set all to yes
This is what solve the problem for me :
Navigate to Content → Article Manager / Parameters (icon top right)
Scroll down to Filtering Options, highlight all Filter groups except Super Administrator, and select Filter type of Blacklist

You could also set the editor as No Editor in the Global Configurations and edit the article.

Answer 3

Go to: plugins/editors/tinymce
open tinymce.php
Find this
Found this section:
// advimage
$advimage = $this->params->def('advimage', 1);
if ($advimage)
{
$plugins[] = 'advimage';
$elements[] = 'img[class|src|border=0|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name|style]';
}
add |usemap after style, just like:
// advimage
$advimage = $this->params->def('advimage', 1);
if ($advimage)
{
$plugins[] = 'advimage';
$elements[] = 'img[class|src|border=0|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name|style|usemap]';
}
