Nuclos embeds the image at runtime by file/image name. Upload it under Configuration → Others → Resource.

The new resource must be assigned to the nuclet – otherwise the report reports that the image cannot be found.

Images from report data (dynamic)

To show images from the database:

  1. Create a field referencing the image (e.g. User_Photo).
  2. Set the field Class to java.io.InputStream.
  3. In the Image tab open the expression editor and set the field as the Image Expression.
