Now do a right-click on the image and choose the last option (In German it's Grafik formatieren, I don't know what it is in English). In 'Position', normally move object with text or something like that is hooked. If it is so, click it, that it doesn't move with the text. Right beside 'Position' is another option, Textfluss in German. Click on Transparent. Then click OK. If the picture has moved down, move it up again. Open the menu again and click on the the option right beside Transparent. It should be named Without or something like that. On 'Graphic', set the colors to grey and the brightness to 70.
