first, I must to thanks the author for this plugin !
It's great, and the default design is really awesome ! :)
By the way, I have a problem with accentuated characters in filenames..
I mean, I have lots of pictures that contains accents like "é", "è", etc.
And when I'm importing them to the Gallery, thumbnail can't be created, and images cannot be viewed.
If this can help, the name which appeared in the admin is for example :
Original name : béatrice.jpg
Admin name : b%c3%a9atrice.jpg
So the characters are encoded but don't work..
NOTE : It gives me an error : "Couldn't load the media file.Error #2035" on the gallery.
