Removing some {block} stuff

[qroft]

Hi,

i am new to Prestashop and startet a total new theme based on the Starter Theme.

I do understand and like the {block} and {hook} workflow that comes with Prestashop, but sometimes i ask myself

if i simply can remove a block information or not.

 

An example about what i mean, i have this inside the product.tpl file:

  {block name='product_thumbnail'}
    <a href="{$product.url}"><img src="{$product.cover.medium.url}" data-full-size-image-url="{$product.cover.large.url}"></a>
  {/block}

Would it be a total mistake to remove the first and the third line and simply make it look like the following?

    <a href="{$product.url}"><img src="{$product.cover.medium.url}" data-full-size-image-url="{$product.cover.large.url}" class="ui fluid image"></a>

Thanks in advance and have a nice weekend!
