In System Preferences, there is an option to include a URL to an image that will be included in report headers. You can find this option in System Preferences > Andar Reports > MIG > Report Headers > URL for report header image.
Some customers have encountered inconsistency in whether these images are displayed in all reports. This is typically due to how quickly the image may be retrieved from the network location as the report writing program will skip the image if it cannot be retrieved in two seconds. A solution to this challenge is to save the image in your File Library and use the URL from the File Library location.
