Streamline theme variant images not working

Topic summary

Main issue: Variant-specific image swapping in the Streamline theme is not behaving as expected. Selecting a color option (e.g., red or white) does not filter the gallery to show only images for that variant; instead, the theme merely scrolls through the image bar on the left.

Desired behavior: When a color variant is chosen, only the images associated with that variant should display, and switching to another color should replace the gallery with that variant’s images.

Context: The poster is seeking guidance and cannot find a fix within the theme settings or existing documentation.

Technical note: “Variant images” refers to product images mapped to specific options (such as color) so the gallery updates based on the selected variant.

Status: No solutions or workarounds provided yet; issue remains open and the user requests help.

Hello, this is my first time using this Shopify question thing because i really cant find a fix.

I’m using the streamline theme and I want to get my products variant images to be different with the color; so like if I pressed on the color red for my product all the images with the red variant would pop up and same thing with the white option; the red images would go away and the white images would appear. With the streamline theme it just scrolls down on the image bar on the left; if anyone can help it would be greatly appreciated it
