Smart ARENA supports image formats like JPG, PNG, and BMP. If your image is in a PDF document, you’ll need to convert it to a compatible image format first. You can use online tools, such as iLovePDF, to convert PDFs to JPGs. Once converted, you can easily insert the image into the application.
Use the "drag and drop" feature to place the image on your step in the content. The image field is located under Basic elements.
If you want a different position, look at different layouts in the left-side menu.
