How to export files from surveys?

Hi Qualtrics experts, I am designing a script to download the survey responses using the API, and then I have to upload those responses to another system. However, I found an issue while retrieving all the information from the responses. I thought that once that you retrieve all the information of a survey, or you get a specific response, all the data will be downloaded. But the problem is that if there is an image, the API will not be able to download it. Unfortunately, my survey has some questions that make the participant draw something. Those responses get saved in Qualtrics as jpeg files with a specific ID, something like F_XXXXXX. So, does anyone know how can I retrieve those pictures?
