Hide or Remove images from main post.

Greetings,

I’m using the following snippet

<?php
   ob_start();
   the_content('Read the full post',true);
   $postOutput = preg_replace('/<img[^>]+./','', ob_get_contents());
   ob_end_clean();
   echo $postOutput;
?>

to hide images from the main page but I’m then calling my images back in a separate div right next to my post but it pulls the captions from below the images to the body of the post. Is there anyway to hide images in a simpler manner so that all of text isn’t being dragged into the same area?

Sorry if this is too vague.

The reason I’m calling the images separately into a div next to the post is because I’m working on a horizontal layout. If anyone has any suggestions, that would help.

Thank you.
