If attribute value equals to... show something

I'm working on something on wordpress + woocommerce. I've inputed some 'filter' attributes value for some products.

So if the value of the attribute for this product includes a "Wood Grains" value, i want to echo an Woodgrains.jpg on the front end.

Therefore if the value = Texture, i want to echo Texture.jpg icon.

the code below is what i've mustered so far, but this only echoes out all the values tagged to a product, i can't figure out what to change to get the 'if' statement in it.

$terms = get_the_terms( $product->id, 'pa_filter');
foreach ( $terms as $term ) {
echo $term->name;
}

here's a screenshot of what the code above does on the front end: http://edleuro.com/new/wp-content/themes/mystile/img/1.png

foreach prints Warning: invalid argument supplied for foreach()…

This works for me "on a purely":

if ( is_product() && has_term( 'Wood Grains', 'pa_filter' )) {
    echo '<img src="Texture.jpg">';
}

i found a better way to resolve my problem. i had this in my content-product.php woocommerce template.

<?php
    $terms = get_the_terms( $product->id, 'pa_filter');
     foreach($terms as $term){
     if($term->name == 'Wood Grains'){
         echo '<img src="icon_woodgrains.gif">';
     }
    }
?>

do take note that the term name is case sensitive.

If this returns an array of terms for the said product:

$terms = get_the_terms( $product->id, 'pa_filter');

You can check if the returned result array has what you are looking for by doing this:

if (in_array("Wood Grains", $terms))
{
    // has it
}
else
{
    // doesn't have it
}

Update

Based in your reply to my answer, I have came up with the following:

Create a helper function like this:

function termExists($myTerm, $terms)
{
    if (is_array($terms)) {
        foreach ($terms as $id => $data) {
            if ($data->name == $myTerm)
                return true;
        }
    }
    return false;
}

Then you use it like this:

if (termExists('Wood Grains', get_the_terms($product->id, 'pa_filter')))
{
    // term exists
}
else
{
    // does not exists
}
