When passing an image file to ImageJ, it does not like '%' in the file name. If the ImageViewer has a title, the file name is derived from it.

It took me a moment to figure out the erase remove idiom below:
https://en.wikipedia.org/wiki/Erase–remove_idiom
But if I understand it, since you are constructing the string here you can do something like
std::string n(name.begin(), std::remove_if(n.begin(), n.end(), &IsBadCharacter), n.end());
But tangental to the PR.

Yeah, looking at this old code it's not the way I'd do it now, but oh well.
Also, I tried out every other non-alphanumeric character and ImageJ didn't have problems with them.
