Links to non-image files can be uploaded to cloud storage from your event site, then you can provide access to them via links (from text or image) in any of the custom text spaces on the public pages of your event site.
Non-image files can be added in any text areas using the HTML Editor. All public pages display an Edit link or icon to Admin/Chair users which provides access to an HTML Editor tool.
Uploaded files must be formatted as .pdf .csv or .xslx
These instructions cover uploading non-image files, then linking them to text or an image. You can find more comprehensive instructions for uploading custom images here.
