I recently changed my naming conventions for files to upload to VPhot.  I wanted to have something like:


Where the V in parentheses was the filter.

However, it looks like VPhot doesn't accept files with parentheses in the name.  It just fails silently and the image never appears in my image list.

If I change it to:


Then it is uploaded and processed correctly.

As far as I know, parentheses are legal in Unix filenames and I assume VPhot is running on some variant of Unix.  Any reason these characters are not allowed?
