Board Game Arena

Hi everyone,
I uploaded an image that is not working because of a French special character (é) in the image name.
When I try to delete this image while editing the Sandbox game by editing the appearance of an object with the image manager, I got an error message:
"Unexpected error: Bad argument type: image should be a file name (xxxéxx.jpg)"

Is there a way to access directly the images repository of a Sandbox game to hard delete this image?

I could keep up with this wrong name but now everytime I load my game I have an error message "Can't load image: xxxéxx.jpg", which is particularly annoying.

Yes, accents can sometimes be troublesome... I removed this image, it should be good now.

Thanks Een!
