Generate theme previews

By default, modules in Add modules show stock thumbnails. Turn on custom thumbnails to replace them with images rendered on your portal, so each module shows your theme's colors, fonts, and spacing. The option is available for Sprocket Rocket themes. A theme added through Add theme with A theme already in HubSpot has no switch: its thumbnails are rendered on the portal automatically.

1. Open an installation and select Add modules.
2. Select the gear icon next to the module search.
3. Turn on Custom Thumbnails. The first time you turn it on, Sprocket Rocket starts generating thumbnails.
4. To refresh them later, for example after changing theme settings, select the refresh icon beside Custom Thumbnails.

Only installed modules can be rendered on your portal. If some modules are not installed, the app tells you how many are missing. Install them from that dialog first, or select Generate Anyway. Modules that are not installed keep their default thumbnails.

Thumbnails generate in the background and can take a few minutes. You can keep working while they run. To refresh a single module, open its menu in Add modules and select Update thumbnail.
