Magento – Call Custom Template in CMS Page

You cannot change the template for a static block because the static block does not have a template. Take a look at the method: Mage_Cms_Block_Block::_toHtml(). The _toHtml() method is used to render any block object, and in the case of the cms blocks it only renders the content of the block.

If you want to wrap the content of any cms block in some markup you can try this:

{{block type="core/template" template="custom/block.phtml" block_id="some_block_id"}}

And in the file custom/block.phtml do this:

<?php
$block = Mage::app()->getLayout()->createBlock('cms/block')->setBlockId($this->getBlockId()); //retrieve the cms block with the id set on this layout block
$html = $block->toHtml();//in this var you have the content of the cms block 
?>
<?php if ($html) : //this is needed to avoid additional markup if the cms block is empty?>
<div class="some-class">
    <div class="some-other-class">
        <?php echo $html;//actuall cms block?>
    </div>
</div>
<?php endif;?>

I hope this is what you needed.

I may be totally wrong, but you can call it like this

{{block type="cms/block" block_id="home_image-center"}} 

in cms -> homepage-> content : in that click show/hideeditor past above code it's work
