In a loop, do not display content that does not have a thumbnail

Question

In a multisite installation, I have a loop set up on my main blog that displays all posts from sub blogs, along with a thumbnail image. The image is important and without one will break the grid.

Is there a way to reject posts that do not have a featured image?

Thanks.

Try to use the has_post_thumbnail function. From the codex:

<?php 
//This must be in one loop

if(has_post_thumbnail()) {
    the_post_thumbnail();
} else {
    echo '<img src="'.get_bloginfo("template_url").'/images/img-default.png" />';
}
?>
