The name, description and image have to be displayed, the height/wifth in pixel/% and the rolling speed have to be specified, and some links like: "Plus" to go to the complete feeds page. (see it live in the first column of the [login to view URL] website). You can find the attached PDF of the waited results. If my explainations are not clear enough, plse PM. Regards.
