How To - "Specify Image Dimensions"

[Soapa]

For my website I did a test with - http://gtmetrix.com/reports/soaparcadia.com/6xaBlYX8

You can see that my website scores not so good regarding the "Specify Image Dimensions'' 

I think it needs to be resolved in the themes/leodrin/modules/homefeatured/homefeatured.tpl file 

And that this is the line of code that I think that needs to be changed.

<img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home_leodrin')}" height="{$homeSize.height}" width="{$homeSize.width}" alt="{$product.name|escape:html:'UTF-8'}" />

Very very much appreciated if you could help me. 

How to change this line of code? 

Friendly Regards
