Viewer is WAY better !

This is probably the fastest JPEG viewer on the Mac. Here's the small problem I have: I assign the default viewer as ViewIt then open one single image in a folder of images. I'd love to switch to thumbnails by pressing ENTER (or by double-clicking), or switch to the next image in the folder (by scroll wheel or cursor keys). AFAIK if on startup I open a single image, ViewIt does not allow me to do that, whereas if I open the folder in thumbnails view (via Finder contextual menu, for example) I can do that switch.
Other than that, excellent. Thank you.

I thought I'd just add a little update to my earlier review (2009). The developer has done a great job of stabilizing this software, although a few problems still exist. When it dos its job it is a marvel, and rapidly opens hundreds of files creating a visible light-box catalog,making additional operations - like renaming, rotation, file conversions and so on - to be performed with an ease and simplicity few 'imaging' apps can claim. Its film-like scrubbing option (allowing a review of the entire set by clicking and scrolling) allows time-lapse sequences (from stills) to be 'previewed.' This was likely not a planned feature, but it is certainly useful for those of us producing time-lapse sequences.

Some of the 'missing features' of this program will - hopefully - be addressed in the future. One of these shortcomings is the program's single preview size limitation. Thumbnails should be available in at least a few convenient sizes, if not being altogether scalable (the ideal). Similarly, the ability to scale this scrubbable preview 'movie' would make time-lapse previews from hundreds (even thousands) of stills more viable (the author should plug this feature, as it is unique). This might be possible for those of us with lots and lots of ram, or a virtual 'ram' solution might suffice. Also, the ability to export a simple movie at these thumbnail sizes could entice a whole new type of clientele into his customer base.

Overal, this is a must have utility for serious photographers who do a lot of shooting. Yes, I use Aperture, and iPhoto still holds most of my research photography from the web, but ViewIt is also a valuable asset to my software arsenal. This is not just a one trick' pony', and if the author chooses to add a few of these suggested features, it becomes an irreplaceable asset.

Encourage him. Buy a copy. I did!

Ditto on the files # limitations. I have had it crash when attempting to load a series of larger TIFFS as well, and this is problematic because modern cameras are producing ever larger files (the Canon 5D Mark II is now at 21 MP!).

Overall, I haven't seen any features added in a long time, either. Something as simple as a movie viewing capability - allowing a series of time lapse shots, for example, to be views a a real-time 30 fps video - might be nice, as the preview already does a nice job of this. You can drag in the MAIN view and see a series of thumbnails that - once the previews are loaded) will let you scrub back and forth nicely. So, why not add a movie playback at one or more speeds?

Overall, a nice fast viewer that reduces the need to boot up PS. However, either this gets updated soon, or it may be time to for some of us to move on.

Definitely a Buyer Beware product at this point, because the developers don't respond to email. If you want to just use this as a viewer this or Viewer Lite would probably be sufficient, but then if you just needed a viewer you probably would stick to your included version of Preview. The things I was looking for was a viewer with some better than average, but not monster Data Asset management type tools. Anyway this has the basic tools I need, but it is unstable while attempting to sort image sets of, probably close to 1,000 and definitely unstable beyond that. ViewIt could also use a GUI icon overhaul, but unfortunately it looks as is the company has elected to stop active development on it. This is bad, because they have not stopped the service to take money for the app and I'm felling a but duped. Essentially, if you don't have many images ViewIt might be a good option for organization, if however you have a lot of images or just aren't comfortable paying for a something from a company that's no longer actively developing software keep looking.
