Form (Image) Documentation
Display image asset files internally and externally with the Form (Image) component
Only files saved as assets and enabled for external users are available for form images. To create a new image file, navigate to the files tab within the app menu, then click the "Upload Asset File" button. Next, select your file, then ensure that "Let guest users see this asset file on public and login pages" is enabled.
Note: only images with a file type (PNG, JPG, JPEG, SVG) are valid for form images.
