When you use a Gallery view in Notion, each item displays a large preview image. Many users are unsure whether that preview comes from the page cover or from an image property inside the database. This confusion leads to inconsistent layouts and missing thumbnails. This article explains the difference between the two image sources, shows how to control which one appears, and helps you avoid common display problems.
Key Takeaways: Notion Gallery View Image Sources
- Gallery card preview priority: Notion uses the page cover image first if one is set; otherwise it falls back to the first image property in the database schema.
- Image property column order: The position of an image property in the database table determines its priority when no page cover exists.
- Page cover vs property image: Page covers are unique per page and appear at the top of the page; property images are database fields that can be the same across multiple pages.
How Notion Chooses Which Image Appears in a Gallery Card
Notion Gallery view displays one image per database item as the card preview. The software follows a strict priority order to decide which image to show. Understanding this order prevents unexpected blank cards or duplicate images.
The priority is: page cover image first, then the first image-type property in the database column order. If neither exists, the card shows a placeholder icon with the page title. This rule applies to all Gallery views, whether they are full-page databases or inline databases inside a page.
Page Cover Image
A page cover is the large banner image at the top of any Notion page. You can set it by hovering over the top area of a page and clicking Add Cover. The cover image can be uploaded from your computer, selected from Notion’s built-in gallery, or linked from an external URL. Each page has exactly one cover image, and it is independent of any database properties.
Property Image
A property image is a database column with the type set to Files & Media. In that column, each row can contain one or more image files. When you upload an image into a Files & Media property, Notion stores it as an attachment to that database item. Unlike page covers, property images can be the same value across multiple rows if you duplicate a cell or use a formula to pull from another source.
Steps to Control Which Image Displays in a Gallery Card
You can force Notion to use either the page cover or a specific property image. The method depends on whether you want to set a unique cover per page or rely on a shared database field.
Method 1: Set a Page Cover to Override the Gallery Preview
- Open the database page
Click the page title in the Gallery view to open the full page for any item. - Add a cover image
Hover over the blank area above the page title. Click Add Cover. Choose from Unsplash, upload a file, or paste a link. - Return to the Gallery view
Click the back arrow or the database name in the breadcrumb. The card now shows the cover image you set.
Method 2: Use a Property Image When No Cover Is Set
- Ensure a Files & Media property exists
Open the database and click the + icon in the last column header. Select Files & Media as the property type. - Move the property to the first column position
Click and drag the property column header to the leftmost position in the table view. Notion reads columns left to right to determine priority. - Upload images into the property
Click inside the property cell for each row and upload an image. The Gallery card will display this image if no page cover exists for that item.
Method 3: Remove a Page Cover to Force the Property Image
- Open the page with the unwanted cover
Click the page title in the Gallery view. - Remove the cover
Hover over the cover image. Click the three-dot menu in the top-right corner of the cover. Select Remove Cover. - Verify the fallback
Go back to the Gallery view. The card now shows the first image property instead of the removed cover.
Common Mistakes When Managing Gallery Images
Gallery Card Shows No Image Even Though a Property Has an Image
This happens when the Files & Media property is not the first image-type column in the database. Notion only checks the first image property it encounters when scanning columns left to right. Move the property to the first column position, or remove any other Files & Media columns that appear before it.
Gallery Card Shows the Wrong Image After Duplicating a Database
When you duplicate a database, Notion preserves the page covers but resets the column order in some cases. After duplication, check that your image property is still in the first column position. Reorder it if necessary.
Image Property Displays as a Small Thumbnail Instead of a Full Card Preview
This is not a bug. Notion always displays the image property as a small thumbnail inside the cell in table view. The full-size card preview only appears in Gallery view. To see the image larger, switch to Gallery view or click the cell to expand the image.
Page Cover Changes Are Not Reflected in the Gallery View Immediately
Notion caches Gallery view thumbnails for a few seconds. If you change a page cover and the card does not update, refresh the browser page or close and reopen the database tab. The new cover appears after the cache clears.
Page Cover vs Property Image: Key Differences
| Feature | Page Cover | Property Image (Files & Media) |
|---|---|---|
| Location | Top of the page, above the title | Inside a database cell |
| Uniqueness | One per page, can be different for each item | Same image can be used in multiple rows |
| Gallery priority | First priority if set | Second priority, only if no cover exists |
| Edit method | Hover over top area, click Add Cover | Click the cell in the database table |
| Supported formats | JPG, PNG, GIF, SVG, and Unsplash links | JPG, PNG, GIF, SVG, PDF, and other file types |
| Visible in table view | No | Yes, as a small thumbnail |
Notion Gallery view gives you two ways to control the card preview: page covers for individual customization and property images for database-level consistency. Use page covers when each item needs a unique visual identity. Use a Files & Media property when you want the same image source for multiple items or when you need the image to be searchable in database filters. For the best control, keep only one image source active per item and verify the column order in your database.
