Hey,
I'm using images to explane my questions in the survey. Is there a way to make a button of the image in the survey and when needed tap this button to open the image? It would make a big difference because now the survey is a bit unclear because of all the big images.
You should be able to utilize the "media::image" field within Survey123 Connect and the media folder within the actual Survey123 folder that resides on your machine. I use this to help demonstrate certain aspects of our surveys.
Take a look at this help article - Style your survey—Survey123 for ArcGIS | ArcGIS
Good Luck!
