How to have separate images between desktop and mobile?

[samueljoonjung]

The image banner on the mobile looks really good but it is way too big on the desktop. What I want for the desktop image is to look like this---the image with the wide black background. And the current image for the mobile cuz it looks perfect on mobile right now. How do i make this change? My url is www.whoglobal.shop

Hi @samueljoonjung ,

You can use the <picture> tag to serve different images based on screen size. This is a clean and efficient way to handle responsive images.

Replace your existing banner image code with the following:

<picture>
    <!-- Desktop Image -->
    <source srcset="your-desktop-image.jpg" media="(min-width: 769px)">
    <!-- Mobile Image -->
    <img src="your-mobile-image.jpg" alt="Banner Image" class="responsive-banner">
</picture>

• The <source> tag specifies the desktop image and applies it only if the screen width is 769px or larger.
• The <img> tag acts as a fallback, displaying the mobile image by default (for smaller screens).

Please be more specific. How do i find the existing banner image code. And what is the banner image code?

[oscprofessional]

To find the banner image code:

1. Inspect the page → Right-click the banner > Inspect > Look for an <img> tag or background image.
2. Check theme files → Go to Online Store > Themes > Edit Code, then look in sections/banner.liquid, hero.liquid, or theme.liquid.

Replace the existing banner code (if using an <img> tag):

<picture>
    <source srcset="your-desktop-image.jpg" media="(min-width: 769px)">
    <img src="your-mobile-image.jpg" alt="Banner Image">
</picture>

If it's a background image, you'll need to update the CSS instead.
