Requirements:             eGroupWare 1.x, htmlArea 3rc or higher
Note:                     UploadImage only works as plugin for htmlArea in eGroupWare.
-----------------------------------------------------------

UploadImage adds an image_upload-icon in the htmlArea-toolbar. When the icon is clicked 
the user can Select an image from the Upload Directory or upload an Image to the directory 
the upload directory eGW-developer has specified. After insertion the image is shown in the 
htmlarea. Future features will be: resizing images, cropping images, rotating images etc ....

To use the plugin you have to do the following:

// thirst setup the sessionvariables UploadImage Need
$sessdata = array(
		'UploadImageBaseDir' =>  /path/to/eg/egw/images ,      // absolute path to the base directory
		'UploadImageBaseURL' =>   http://yourhost/egw/images,  // the complete URL to the base images directory
		'UploadImageMaxWidth' =>  500,                         // max, image width in pixels
		'UploadImageMaxHeight' => 500                          // max. image height in pixels 
		);

$GLOBALS['phpgw']->session->appsession('UploadImage','phpgwapi',$sessdata);


// then init the html class and call the htmlarea class-method with the UploadPlugin as argument
if (!is_object($GLOBALS['phpgw']->html))
{
	$GLOBALS['phpgw']->html = CreateObject('phpgwapi.html');
}

$htmlarea = $GLOBALS['phpgw']->html->htmlarea($field_name, $value,$style,false,'UploadImage',$custom_toolbar);

SECURITY WARNING!!!
-----------------------------------------------------------
When you are implementing the UploadImage plugin make sure 
your UploadImageBaseDir is set correctly because else it 
might give access to other directories apache has access to.
