I guess it's OK for you to upload it, I really don't mind. Work on the new costume viewer has been postponed anyway so if you'd have to wait for the new version you'd probably have to wait for a really long time.
But beware, this program has some nasty bugs, especially when browsing the costumes from Day of the Tentacle or Sam & Max. I never finished support for those two games but you can still open them in the program. Some costumes work, others don't.
Well, anyway, have fun. And please, no bug reports.
And jannar, the zip archive is broken...
