filenames are stored encoded in the xml. Therefore I don't think so.
if you have a filename like:
!@#$%&.jpg
I store this urlenoded:
%21%40%23%24%25%26.jpg
And I do check every time in an xml if the file still exists - therefore this should not be a problem either ...
But a good idea would be to clean up xml's sometimes... Removing entries that do not exist anymore. But I don't want to do this automatically because if you e.g. only move something the the data is lost right away ...
But I have to add this function with the "construction site". (You can e.g. disable the gallery then if you e.g. want to change something and you don't want that anyone accesses the gallery meantime - it's on my todo for 1.
