I needed to finally buy an app to catalog my stock photos, clip art, and job graphics. I had the free iView Media 1.0 that came with my Mac, but because I didn't want to upgrade it (due to cost and the fact it is now MS) I demoed all the contenders listed on MacUpdate. I narrowed it down to QPict and Mediaboard One, which I then put head to head. I started with QPict which had various crashes. I did like a couple things about it so I attempted again. I soon realized it really didn't have the flow and organization that I wanted. As it imported, it automatically interpreted the categories, and folders, which at first I thought was a good thing. But then when I looked at all of that stuff listed in the organizer window, there were all these listings that were indecipherable from my real organized folders. It also had warning triangles for most of the images. It also skipped over one particular group of nested folders and only listed one random item from it all. Also, if I clicked on a folder from its finder pane, it started indexing it (and you can't cancel the importing) and created a new database. But I gave QPict one last shot and imported my entire library into it, which took an extremely long time (from morning to night). At the very end, when it was doing its final indexing, it crashed, and I lost the whole day's worth of effort. Also, I had the program make references to the real file, not store the actual file, but regardless, the QPict size was huge compared to the database created by Mediaboard One, and even though I have a big hard drive, I don't need the database to be so enormous when Mediaboard One was so much more efficient.
Now Mediaboard One. It organized my files the way I wanted them to be, has lightning fast searches, flexible and time-saving keywording, flexible structure, provisions for bought/sold image info, and very very stable. No crashes at all, and I imported my entire library in half the time as QPict. So I bought Mediaboard One without hesitation. My advice is to take a look at it before committing to QPict.
