or if you just want to run it without making an exe, just double click it (once installing AutoHotKey, of course)

Wow, that's great too, Target.  A couple of things:
The polling doesn't work with my card reader, because when you remove the card, the drive itself still exists (it just says Removable Disk whatever), so your script launches the kiosk every second, which says "No images found, remove card and press OK."  Also, the thumbnails were stretched to fit the square rather than keeping the aspect ratio & whitespace.  Also, when I selected all, then none, rather than clearing the checkboxes, it made them all completely colored in.  Wow, bad word choice.  Here's non-checked: [ ], here's checked: [v], here's "colored in": [#].  When I clicked each individual checkbox, it cycled through those three settings rather than just checked/unchecked.  Finally, I'm not quite sure how to set the destination folder.  Other than that, it's great.
