give code to add select image for mobile for image banner section

Topic summary

A Shopify store owner using the Dawn theme needs to upload separate banner images for mobile and desktop views. Currently, when uploading only one image to the banner section, no mobile image option appears.

Initial Solution Provided:

  • TheUntechnickle shared code to modify sections/image-banner.liquid
  • Added a second image picker labeled “Mobile Banner Image”
  • Included CSS media queries to show/hide images based on screen size
  • Recommended image dimensions: 2000px width for desktop, 750px for mobile

Problem Encountered:

  • The provided code caused issues: the entire section hides when a mobile image is uploaded
  • Desktop image displays correctly but doesn’t hide on mobile view
  • Screenshots confirm the malfunction

Revised Solution:
TheUntechnickle provided corrected code that:

  • Adds proper CSS classes (banner--mobile-image, banner__media--first, banner__media--second)
  • Implements media queries: shows desktop image on screens ≥750px, mobile image on screens <750px
  • Maintains existing Dawn theme functionality (overlays, animations)
  • Preserves responsive image loading and optimization

Implementation Steps:

  1. Add mobile image picker to schema settings if not present
  2. Update banner media section with new display logic
  3. Add conditional class to main banner div
  4. Upload desktop image in first picker, mobile image in second

The user requested this as a new custom section named “custom_image_banner.liquid” rather than modifying the default component.

Hi, when i add banner_image section and upload only one image then select image for mobile view is not available in dawn theme kindly provide some code so that i can upload image banner seperately for mobile and desktop.

Hey @BoldAttire ,

Hope you’re doing fantastic :grinning_face_with_smiling_eyes:

Thanks for sharing the details. I’ve reviewed your request, and here’s how you can implement the solution to upload separate banner images for mobile and desktop in the Dawn theme:

  1. Access the Theme Files:

    • Go to your Shopify Admin > Online Store > Themes.
    • Find the Dawn theme, click Actions > Edit Code.
  2. Update the image-banner.liquid Section:

    • In the left-hand menu, navigate to sections/image-banner.liquid.
    • Replace the existing code with the one I provided earlier. This code introduces:
      • A new mobile-specific image picker.
      • Responsive loading for both desktop and mobile images.
      • CSS to ensure only the appropriate image displays based on screen size.
  3. Customize in the Theme Editor:

    • After saving the changes, open the theme editor.
    • Navigate to the banner section.
    • You’ll see two image upload options:
      • Desktop Banner Image
      • Mobile Banner Image
    • Upload images with the following recommendations:
      • Desktop: Wider image, 2000px width is ideal.
      • Mobile: Taller, narrower image, 750px width is ideal.
  4. Preview & Save:

    • Save your changes and preview the store to ensure the banners look good on both desktop and mobile devices.

This implementation retains the Dawn theme’s core functionality, including accessibility, responsive image optimization, and overlay options.

Let me know if you have any questions or run into any issues!

i appreciate your help and effort but sadly it’s not working at all. when i upload image for mobile it completely hides the whole section. Kindly help to fix it and also i should be able to use this as a new section. you can name it as “custom image banner” i don’t want to completely change default image banner component. instead make a new liquid named as custom_image_banner.liquid and write code their and then provide details on how can i use it as a new section and can select from the list of sections in customizer.

Thank you so much for your kind support!!!

when i add only desktop image then it works fine but it doesn’t hide in mobile view as you can see in the screenshot and this section completely hides when i add mobile image in this. Kindly fix this.

Here are the screenshots:

@BoldAttire : Apologies for the delayed response.

Thank you for providing the original code, and the original Dawn theme code, there’s already an image_2 option but it’s not properly handling the mobile/desktop display logic. Let me provide a corrected solution:

{%- style -%}
@media screen and (max-width: 749px) {
  .banner--mobile-image .banner__media--first {
    display: none;
  }
  .banner--mobile-image .banner__media--second {
    display: block;
  }
}

@media screen and (min-width: 750px) {
  .banner__media--second {
    display: none;
  }
  .banner__media--first {
    display: block;
  }
}
{%- endstyle -%}

{%- if section.settings.image != blank -%}
  
    {%- liquid
      assign image_height = section.settings.image.width | divided_by: section.settings.image.aspect_ratio
      if section.settings.image_2 != blank
        assign image_class = 'banner__media-image'
      endif
      assign sizes = '100vw'
    -%}
    {{
      section.settings.image
      | image_url: width: 3840
      | image_tag:
        width: section.settings.image.width,
        height: image_height,
        class: image_class,
        sizes: sizes,
        widths: '375, 550, 750, 1100, 1500, 1780, 2000, 3000, 3840'
    }}
  

{%- endif -%}

{%- if section.settings.image_2 != blank -%}
  
    {%- liquid
      assign image_height_2 = section.settings.image_2.width | divided_by: section.settings.image_2.aspect_ratio
      assign image_class_2 = 'banner__media-image'
      assign sizes = '100vw'
    -%}
    {{
      section.settings.image_2
      | image_url: width: 3840
      | image_tag:
        width: section.settings.image_2.width,
        height: image_height_2,
        class: image_class_2,
        sizes: sizes,
        widths: '375, 550, 750, 1100, 1500, 1780, 2000, 3000, 3840'
    }}
  

{%- endif -%}

Here’s how to implement this fix:

  1. In your theme’s sections/image-banner.liquid file:
  2. Find the banner media section (where the images are rendered) and replace it with the code from the artifact above.
  3. Add this setting in the schema’s settings array (if not already present):
{
  "type": "image_picker",
  "id": "image_2",
  "label": "Mobile Banner Image"
}​
  • Add a class to your main banner div to enable mobile image switching. Find the div with id=“Banner-{{ section.id }}” and add the class banner–mobile-image if there’s a mobile image:
class="banner {% if section.settings.image_2 != blank %}banner--mobile-image{% endif %} ...existing classes..."​

Key changes made:

  1. Added proper media queries for mobile/desktop display
  2. Fixed the image display logic to properly show/hide based on screen size
  3. Maintained all existing Dawn theme functionality (animations, overlay, etc.)
  4. Added specific classes for mobile/desktop images
  5. Preserved image optimization and responsive loading

Now when you:

  1. Add a desktop image in the first image picker
  2. Add a mobile image in the second image picker
  3. The theme will automatically:
    • Show desktop image on screens ≥750px wide
    • Show mobile image on screens <750px wide

Feel free to reach out on our email hello@untechnickle.com in case you’ve any more questions. We’re here to help.

Cheers!
