Comparing part of a variable value

I have a session whose value is either something like this rose_portraitlg.jpg or this rose_landslg.jpg. The only thing that is constant in these file names is the portrait or lands. I need to be able to compare variable in an if statement to determine if portrait or lands is in the variable named.

$virtualcomp = $_SESSION['virtualimage'];
...

if ( $virtualcomp == portrait) {
echo "<img src='awards/".$_SESSION['virtualimage']."' width='445' height='607'/>";
}

else {
echo "<img src='awards/".$_SESSION['virtualimage']."' width='560' height='430'/>";
}

if (strpos($virtualcomp, 'portrait') !== false) {
echo "<img src='awards/".$_SESSION['virtualimage']."' width='445' height='607'/>";
} else {
echo "<img src='awards/".$_SESSION['virtualimage']."' width='560' height='430'/>";
}

In case you were wondering why if (strpos($virtualcomp, 'portrait') !== false) works

The strpos() function returns the position of the first occurrence of a string inside another string.

If the string is not found, this function returns FALSE.
