Background Images

Recommended background settings

The display size and aspect ratio of your and your users' devices can have a significant impact on how the background is displayed.

When choosing a background image for your Themes, it is recommended to use PNG or JPG file types. The long side of the background image should have a minimum of 2048 pixels.

It's important to keep the subject of the image centered because the background image sides might get cropped depending on the device being used. For example:

• iPads have a 4:3 ratio with dimensions of 2048 x 1536 pixels
• Laptops and monitors have varying aspect ratios depending on the Showell window size chosen by the user
• Phones can have ratios between 16:9 and 20:9 with dimensions of 2048 x 1152/922 pixels.

How to add a background image

1. In the Showell App for Web, Open 'Edit'-Mode from the Home page.
   1. Home page: You can set a wallpaper on the Home level. This will apply to all folders and subfolders by default.
   2. Top-level folders: You can also set wallpapers on top-level folders (the folders directly under Home). These will override the Home wallpaper for that specific folder and its subfolders.
2. Open the Home page or top-level folder Settings
3. Click the 'Change Image'-button:
   • Upload image: Upload a new thumbnail image of choice
   • Select from gallery: Select a thumbnail uploaded to your Application Resources, or then navigate in your content structure to select the right image
   • Edit image: Crop the thumbnail
   • Remove image: Remove the current thumbnail
4. Once you are done with one of the above actions, the changes will be auto-saved
