Kind of stuck on replace and checking empty

[phpnoobie9]

I have a form that I can enter in an image url:

form

<form action="test.php" method="post">
Submit Image Url:
<input type="text" name="image2" size="45" />
Submit Image Url 2:
<br>
<input type="text" name="image2" size="45" />
<input type="submit" name="preview" value="Preview" />
</form>

 

When I submit the url the php code below checks for it..the below is wrapped up in a isset submit.

This page get's the information from the form and replaces the str_replace IMAGE1 or IMAGE2 with what I entered from the url form.

 

What I want is when the image url 1 or image url 2 is empty I want it to echo nothing else I want to echo the string replacement with the img src tag.

 

Can't seem to get it to work.

 

$imageempty = "";//If no url was entered
$image1 = $_POST['image1'];//Get url from form
$image1a = "<img src=\"$image1\" width=100 height=100 >";//Insert url into image tag
	//If image 1 input box empty
	if (!empty ($image1)) {
	//If not empty show this
	$replace = str_replace ("IMAGE1",$image1a,$replace);
	} else {
	//If empty show this
	$replace = str_replace ("IMAGE2",$imageempty,$replace);
	}
