April 2019: NOTE this web page written in 2015 is outdated, as it shows testing the Upload Server with Bonjour. Please see the updated Upload Server instructions for Activator Plug-in 5.
With the functions of Troi Activator Plug-in 3.0 and later your FileMaker Pro database can become an (Image) Upload Server. The Activator Plug-in can receive the uploaded (JPEG) images with user text and even (GPS) location information.
You can test the upload locally with the Safari browser.
