this is more than just a simple feature requests. there are a number of bugs in the tracker that would be solved if hugin would check its list of images before undertaking any further step.

if i knew how and where to code it, i would code a generic function to check/update/reload the list of images.

i would check against location/filename/timestamp

in case of missing location/filename i would raise an exception and prompt the user with a "can't find file XXX" error, rather than continue execution and crash:
<http://sourceforge.net/tracker/index.php?func=detail&aid=1890064&group_id=77506&atid=550441> (0.7.0)
<http://sourceforge.net/tracker/index.php?func=detail&aid=1742019&group_id=77506&atid=550441> (0.7.1)

in case of newer timestamp, i would reload the image (which would solve this feature request).

the function would need to be as fast as possible, because it will become gatekeeper to many functions.

an update button would manually trigger it
