Select Creative > Assets Library.

Click Upload to upload your Workspace and assets.

Create a new ad.

In the Creative Assets section, select the Main Assets tab and define the Workspace Folder and Default Image.

In the Creative Assets section, select the Additional Assets tab.

Click Add Asset.

Navigate to the folder where your assets are located.

Select a file to add as an additional asset.

Click Assign.

To assign assets, create a new folder called AdditionalAssets in the root directory of the Workspace with other files such as index.html and config.js. The name is case-sensitive and does not contain a space.

Save the assets in the AdditionalAssets folder.

The following image shows a Workspace including the AdditionalAssets folder with four images.

After setting up the AdditionalAssets folder, configure the assets in the config.js file. Registering additional assets requires creating a new property named AdditionalAssets. To avoid errors, make sure that all code and comments are inside the define function.

In the config.js file under the AdditionalAssets property, create an object array for each asset with an OrdinalNumber and the asset file.

In the following example, 1 is assigned to the assets1.jpg, and 2 is assigned to assets2.png. You can use these additional assets directly in dynamic elements by putting the ordinal number of the relevant asset in the value of the dynamic element.

define({
    "SV": {
        "svData": [
            {
                "svKey": "pic1",
                "svType": "Image",
                "value": "1"
            },{
                "svKey": "pic2",
                "svType": "Image",
                "value": "2"
            }
         ]
    },
    "AdditionalAssets": [
        {
            "OrdinalNumber": 1,
            "FileName": "assets1.jpg"
        },
        {
            "OrdinalNumber": 2,
            "FileName": "assets2.png"
        }
    ]
});
