Images can be used in a form template to be visible when completing a form and or on the PDF.
Using the images field in the toolbox in the form builder you are able to access images that are in your Resources / Documents or uploaded to the form images tab.
After dragging the image field to the form, select the field and then in the settings, select the Resource, Document, or saved form template image in the Image dropdown.
Remember to Save Draft and Deploy / Publish Template once the changes are made, so that they will be available on any new forms created from the template.
To add an Image to the form template images tab, in the Web Portal go to Forms > Existing Templates > Edit Arrow for the intended template > Images > Add Images.
