## Documentation

By default, DXP contains two Image Resolutions: a Preview and Thumbnail. You can always add more Image Resolutions, such as resolutions to cover common device sizes like mobile phones, tablets, laptops, and desktops. For example, if most users use one device (e.g., all Intranet users have the same company mobile phone), you can create a resolution to target that device. Note that generating more images requires additional computational resources and storage space.

Here you’ll learn how to define the resolutions for the images delivered to users’ devices. Once the resolutions are defined, Adaptive Media then generates new images scaled to fit those resolutions and maintains the original aspect ratio.

Images uploaded before you create a resolution are not affected and must be adapted separately (see Generating Missing Adapted Images).

## Adding a New Image Resolution¶

2. Click the Add icon () on the Adaptive Media configuration page and provide the information below.

3. Click Save when finished.

Name: Enter a unique name. This can be updated if a custom Identifier is defined.

Max Width: The generated image’s maximum width. If a Max Height is given, this field is optional. This value must be at least 1.

Maximum Height: The generated image’s maximum height. If a Max Width is given, this field is optional. This value must be at least 1.

Add a resolution for high density displays (2x): Defines a scaled up resolution for HIDPI displays. Selecting this option creates a new resolution double the size of the original with the same name and the suffix -2x. For example, if the original resolution is 400px by 300px (max width by max height), the high density resolution is 800px by 600px.

Identifier: The resolution’s ID. By default, this is automatically generated from the name. You can specify a custom identifier by selecting the Custom option and entering a new ID. Third party applications can use this ID to obtain images for the resolution via Adaptive Media’s APIs.

Tip

Image resolutions and their identifiers cannot be updated if the resolution has been used to adapt images. This prevents inconsistencies in generated images.
