I've actually not used FOLDERWATCH. When I tried to do something similar before, I instead used widget timer events

http://www.harrisgeospatial.com/docs/working_with_widget_eve n.html#widget_techniques_4218446668_96233

so that every 20 seconds I could perform a file_search() to see if any new files appeared. If a new image appeared I would read it and display it in a widget window.

it looks like one can do the same with FOLDERWATCH using the callback procedure given in the Init method. You could have the callback procedure display the new file in a WIDGET_WINDOW or whatever other method you use for diplaying static images. --Wayne
