@ChrizK each news item in a news web part is a page in its own right. The web part picks up the banner image in the page to use in the web part, or if there isn't a banner image - for example the header layout is set to Plain - then any other image image on the page will be picked up to use in the web part. The amount of text its uses from the page is about the first 100 characters.
