Case description - past images - TinyMCE and HTMLPurifier

Hi.

My current release is 7.9.4 in a fresh install.

When I paste an image to the case description (managed by TinyMCE, I think) and save it, the image is stripped.

I think that the problem is in the HTMLPurifier that remove my img tag from the html source.

I have seen that HTMPurifier defaults are written in [suitecrmpath]\include\clean.php but I have not found how customize this module to allow the img tag and the related attributes.

Can anyone help me?

Solved!

After some searches on HTMLPurifier setup documentation, and several test, I have added in the [suitecrmpath]\include\clean.php config section, at line 102 line, the code:

	$config->set('URI.AllowedSchemes', array('data' => true)); // Damiano 14/08/2017

It work fine, for me.

Now the question is: what is the best practice to add this line of code in the clean.php to keep it in case of update? I am not a developer, I have search in the developer guide but I have not found it.

Thanks
