Posts aren't published correctly

Hello, Another question (maybe a silly one, sorry for that): I created two posts. Both have an image and both have a hyperlink to another website. But when I see them on the home page I only see the text of the posts and the images and links are missing. (Only when I click the article titles the images and links are shown). How is this possible? And how to solve this? The url is http://www.vvelacour.nl Does anyone can give me a clue? Sabine
