# Theme 3.5.3 ### Gallery product detail page The display of the gallery on the product detail page is affected by the breaking changes. The display of the product image may have changed here. ### 1. Checkbox Background In this update, the **background (1)** checkbox has been removed. Instead, a color must be defined in the Background (3) colorpicker field, or if no color is desired, replace it with the value `transparent`. ### 2. Colorpicker background The **Background (2)** colorpicker field has been given a new default value because referencing the previously defined variable `$zen-product-listing-card-img-bg` from *Tab: General > Section: Product Images* can lead to a compile error. According to Shopware, it is not certain that previously defined variables will already exist at a later point. The order of the variables when compiling may differ from the order of defining the variables in the theme configuration. ### 3. Background-color overlay You can use the new checkbox **Background-color overlay (4)** to control whether the background color should be overlaid on the gallery image. This setting was previously taken from the field of the same name under *Tab: General > Section: Product images*.\ \ Description of this functionality: {% content-ref url="../content/product-images/product-image-background" %} [product-image-background](https://themedocs.zenit.design/en/content/product-images/product-image-background) {% endcontent-ref %}
