Help with displaying element from array

My php knowledge is very limited so please help me out.

So basically there's a product with multiple options, containing stuff like image, name, value etc.

$this->data['options'] = array();
			
foreach ($this->model_catalog_product->getProductOptions($this->request->get['product_id']) as $option) { 
	if ($option['type'] == 'select' || $option['type'] == 'radio' || $option['type'] == 'checkbox' || $option['type'] == 'image') { 
		$option_value_data = array();
					
		foreach ($option['option_value'] as $option_value) {
			if (!$option_value['subtract'] || ($option_value['quantity'] > 0)) {
				$option_value_data[] = array(
					'product_option_value_id' => $option_value['product_option_value_id'],
					'option_value_id'         => $option_value['option_value_id'],
					'name'                    => $option_value['name'],
					'image'                   => $this->model_tool_image->resize($option_value['image'], $this->config->get('config_image_thumb_width'), $this->config->get('config_image_thumb_height')),
					'imagethumb'              => 'image/' . $option_value['image'],
					'price'                   => (float)$option_value['price'] ? $this->currency->format($this->tax->calculate($option_value['price'], $product_info['tax_class_id'], $this->config->get('config_tax'))) : false,
					'price_prefix'            => $option_value['price_prefix']
				);
			}
		}

Code (markup):

I have another template file that pulls info from this array:

<img src="<?php echo $option_value['imagethumb']; ?>">

Code (markup):

There are multiple 'imagethumb's from the array. Right now the above code shows the last picture in the array. How can I echo the first imagethumb in the array??

Please help. Thank you.

 

add a counter, starting before the foreach

$counter = 0;

then loop the foreach and the next line should be.

$counter++;
if ($counter == 1) { // display image }
