I created a form with a calculated field with the following expression.
Even if an aws link is in the project's URL field it will tease out the
image info and convert to a workfront URL.
IF(CONTAINS(Project.URL,"amazonaws"),CONCAT("https://havertys.my.workfront.com/internal/document/thumbnail?documentVersionID=",SUBSTR(Project.URL,108,32),"&ID=",SUBSTR(Project.URL,75,32)),Project.URL)
