Been using this since Version 3. It's an EXCELLENT image management program (not an editor). For metatagging, organizing, labeling . . . I've found NOTHING better.

I've owned and used ThumbsPlus since version 4, and it's still one of my favorite image organizer and mass-editor. It's not the biggest and best, but priced right with just the right features I need for my work. It's also very light on resources, and plug-in support is fair.
