Preparing Thumbnail Images
Displaying theme thumbnail images
A complete Stencil theme includes screenshots to display the theme on cards that appear in two locations within a non active MSF BigCommerce control panel:
- Storefront › Themes: Each individual card displays a composite which is an image that contains combination of screenshots of the theme's multiple variations.
- Storefront › Themes Marketplace: Each card displays one variation of your theme. The three variations of Cornerstone (Light, Warm, and Bold) are displayed across three separate cards.
General image requirements
All screenshots described below must meet the following specifications in order for the stencil bundle
command to be able to process them:
- Must be saved to a supported image file type: .jpg, .jpeg, .png, or .gif.
- Must be stored in your meta/ (opens in a new tab) subdirectory.
- Must be in portrait aspect ratio.
Theme-wide composite image
The theme-wide composite image represents your theme in a non-active MSF BigCommerce control panel's Storefront › Themes, which shows merchants their currently available themes, including any custom uploaded themes.
This file will normally be a mosaic of screenshots from multiple variations within your theme. It must meet the following requirements, beyond the general specifications above:
- Resolution of 600 x 760 pixels (horizontal x vertical).
- File size smaller than 2 MB.
- Arbitrary filename prefix, referenced in your config.json (opens in a new tab) file as the
meta
object'scomposed_image
key value.
Here is an example of a compliant file type and location:
meta/composed.png
Here is how you would reference this file within config.json (opens in a new tab).
{
// [...]
"meta": {
[...]
"composed_image": "composed.png",
// [...]
}
Variations: desktop and mobile screenshots
Each variation within your theme must be represented by two additional screenshots if you want that variation to appear in a non-active MSF control panel's Storefront › Theme Marketplace, which shows merchants the themes that are available for download.
Desktop screenshot
The first screenshot, showing your theme on a desktop viewport, must meet the following requirements beyond the general specifications above:
-
Resolution of 2048 x 2600 pixels.
-
File size smaller than 5 MB
-
Arbitrary filename prefix, referenced in your config.json (opens in a new tab) file as the
variations
object'sdesktop_screenshot
key value.
Mobile screenshot
The second screenshot, showing your theme on a mobile viewport, must meet the following requirements beyond the general specifications above:
-
Resolution of 304 x 540 pixels.
-
File size smaller than 1 MB.
-

variations
object'smobile_screenshot
key value.
Below is an example showing two files of compliant types and location.
meta/desktop_bright.png
meta/mobile_bright.png

"variations": [
