Change Thumbnail Size on Product Pages

Topic summary

A user seeks to modify the thumbnail size for product page images, specifically the small stacked images displayed on the right side of the page.

Initial Solution Attempted:

  • A CSS code snippet was suggested to add to section-main-product.css:
    .thumbnail img {
        object-fit: contain !important;
    }
    

Current Issue:

  • The proposed code does not change the thumbnail dimensions as needed.
  • When the user manually adjusts the size, the thumbnails become partially covered by the main product image due to overlap.
  • The user needs a solution that both resizes the thumbnails and repositions them to prevent this overlap.

Status: The issue remains unresolved, with the user awaiting further guidance on proper CSS adjustments for both sizing and positioning.

Hi there Joey! @JoeyRoo

I suggest that you add this code at the bottom of section-main-product.css file

.thumbnail img {
    object-fit: contain !important;
}

Don’t forget to let me know if you found this helpful!

This dose not change the size of the thumbnail images. I want to change the size of the small stacked images on the right hand side. I am able to change their sizing, but when I do that, they end up being slightly covered by the main image so I need to be able to change their size then also move them over so there is no overlap
