Globiflow needs the original URL of the image to display it in the PDF. But your calculation field, which displays the image, doesn't give this URL to Globiflow (Globiflow can't recognize "!(" + link1 + ")" as a URL) . A workaround in Globiflow is: Add an action "Get referenced items" from the app where the field Image Link is in. Then a token [(Ref app) Image Link] is available. This token you can insert into the PDF builder.
