Make images look bigger on mobile

[anlupapeltapiz]

Hello,

I want to make some of my images bigger but only on the mobile version and only on that page (i want the rest of the images on my web to look the same).

How can i fix it?? I attach the images.

If you're using a Shopify free theme, while on a paid plan, then this would be a request we can escalate to our Themes team. You can create the request by contacting Shopify after logging into your store through the help center, searching your question/issue, then selecting "continue" at the bottom of the page that displays the search results. 

If these are instructions, then it may be easier to offer the instructions via a PDF file that customers can download. You can upload the file to Settings/Files, then hyperlink the URL to your product page.
