Hide Empty Fields

How do I hide a line if there is nothing in the database field?

Like this line:
<p> Description: <?php echo $row_WADAProperties["ShortDes"]; ?></p>

If there is nothing in the in the info field of the table can I hide the entire line?

Same goes for an image. If there is not an image can I hide the area that image would show?

<img src="PropsAdmin/images/<?php echo $row_WADAProperties['imageOne']; ?>" alt="<?php echo $row_WADAProperties['PicOneTitle']; ?>" width="227" height="198" class="Lefty PrettyPicSM" /><br />
<p> <?php echo $row_WADAProperties['PicOneTitle']; ?> </p>

I have tested some If statements but not working it out yet.

PS How do I surround code blocks on this forum?

use an if statement with the != comparison. != means Not Equal:
if($row_WADAProperties["ShortDes"] != "") {....}

<?php if($row_WADAProperties["ShortDes"] != "") { ?>

<p> Description: <?php echo $row_WADAProperties["ShortDes"]; ?></p>

<?php } ?>

<?php if($row_WADAProperties['imageOne'] != "") { ?>

<img  src="PropsAdmin/images/<?php echo $row_WADAProperties['imageOne']; ?>" alt="<?php echo $row_WADAProperties['PicOneTitle']; ?>" width="227" height="198" class="Lefty PrettyPicSM" /><br />

<p> <?php echo $row_WADAProperties['PicOneTitle']; ?> </p>

<?php } ?>
