Thx krus for you answer! I've found a nicer way to solve the problem with the cached image URLs. I even had to do this, because your solution overwriting the Widget Model didn't work with Magento 1.7.0.2.

So what I have done is adding a new GET parameter use_file_url to the URL used for the Chooser Block:

$url    = $this->getUrl(
    '*/cms_wysiwyg_images/index',
    array(
        'target_element_id' => $element->getName(),
        'use_file_url' => 1
    )
);

This passes the GET parameter to the media browser. The next step is to pass this parameter to the onInsertAction of the Mage_Adminhtml_Cms_Wysiwyg_ImagesController. Do do this, you have to override the getOnInsertUrl() function of the Mage_Adminhtml_Block_Cms_Wysiwyg_Images_Content Block:

public function getOnInsertUrl()
{
    $useFileUrl = (int)$this->getRequest()->getParam('use_file_url', 0);
    return $this->getUrl('*/*/onInsert', array('use_file_url' => $useFileUrl));
}

Then you need to handle the new parameter in the Mage_Adminhtml_Cms_Wysiwyg_ImagesController controller:

public function onInsertAction()
{
    $useFileUrl = (int)$this->getRequest()->getParam('use_file_url', 0) == 1 ? true : false;
    $helper     = Mage::helper('cms/wysiwyg_images');
    $storeId    = $this->getRequest()->getParam('store');
    $filename   = $this->getRequest()->getParam('filename');
    $filename   = $helper->idDecode($filename);
    $asIs       = $this->getRequest()->getParam('as_is');

    Mage::helper('catalog')->setStoreId($storeId);
    $helper->setStoreId($storeId);

    if ($useFileUrl == false) {
        $image = $helper->getImageHtmlDeclaration($filename, $asIs);
    } else {
        $image = $helper->getImageMediaUrl($filename);
    }

    $this->getResponse()->setBody($image);
}

The last step is to override the Mage_Cms_Helper_Wysiwyg_Images helper and add the getImageMediaUrl() function:

public function getImageMediaUrl($filename)
{
    return $this->getCurrentUrl() . $filename;
}

I think this is a quite pretty approach, even though you have to ovverride 4 classes. But passing a GET parameter seems to be more future safe than parsing the cached URL.
