[TYPO3-mvc] RTE remove absolute image URLs

[Andrea Schmuttermair]

Hello,

I have a Extbase Extension with a RTE Text field.

If I insert images with the image icon, I get absolute image links:
<img src="https://www.mydomain.com/uploads/RTEmagicC_MyImage01.jpg"  
height="325" width="952" />

But I want relative image links. How can I change that?

This is my TCA field configuration:
'content' => array(
             'exclude' => 0,
             'label' => 'content',
             'config' => array(
                 'type' => 'text',
                 'cols' => 40,
                 'rows' => 15,
                 'eval' => 'trim,required',
                 'wizards' => array(
                     'RTE' => array(
                         'icon' => 'wizard_rte2.gif',
                         'notNewRecords'=> 1,
                         'RTEonly' => 1,
                         'script' => 'wizard_rte.php',
                         'title' =>  
'LLL:EXT:cms/locallang_ttc.xml:bodytext.W.RTE',
                         'type' => 'script'
                     )
                 )
             ),
             'defaultExtras' => 'richtext[]',
         ),

Thank you,
Andrea
