Viewing Gantt charts within Dropbox

Hi all, I’m new to using GanttProject but very capable on MS Project. My burning question is if i produce a Gantt chart and want others to view it, do the others have to download the software or is there a way of simply viewing. I’ve just tried to hyperlink a Gantt within Dropbox so other users within the Dropbox group can view it. However, (online) it comes up as not available. Any advice is gratefully appreciated.

The easiest way to share Gantt chart for viewing is to export it to PNG and put the Picture file to Dropbox.
