How to Display only 3 related product on product view page, Magento?

Question

I am displaying related products in content block of layout in product view page. My code in catalog.xml is:

<reference name="content">
     <block type="catalog/product_list_related" name="catalog.product.related" after="-" template="catalog/product/list/related.phtml"/>
</reference>

Now, all the related products are displayed in my product view page, but I want to display only 3 products, What should I do? Please, anybody can help ??

You need to edit the template file catalog/product/list/related.phtml and limit the loop to only iterate through 3 products.

For example:

    ...
    <?php $i = 0; ?>
    <?php foreach($this->getItems() as $_item): ?>
        <?php if($i++ == 3) break; ?>
        ...
