convert a text with images out of wordpress into an image

Hi, i have got a wordpress blog working quite fine. the shop lookes like: (It is only dummy text) [login to view URL] look at the article-part (notNavigation / sidebar) at "Produktbeschreibung" you should create a php script, that converts the text (with the image) into one image the result should be like this [login to view URL] with the created image: [login to view URL] the wordpress function $text= the_content() will serve text and image and nothing more the image should be automaticly saved on the server.
