I need shopify code editing for image banner

This e-commerce site requires customization of the Shopify theme code to display differentiated banner images for desktop and mobile users. Currently, the same banner image is displayed across all devices. The objective is to code the theme to intelligently serve a dedicated desktop banner and a different mobile banner optimized for smaller screens. The developer selected for this task will need proficiency editing Shopify Liquid code and theme files. They will modify the relevant sections to check the user's device and serve the appropriate image. Pixel dimensions for the dedicated banners must also be specified to guide image creation. Once development is complete, the client will upload new desktop and mobile banners matching those sizes. This image differentiation will enhance the online shopping experience depending on how customers access the site, whether on a large monitor or smaller phone screen. Device-appropriate banners can better showcase products to viewers on each platform.
