Downloading JustLooking

Version 3.3.3 is the latest version of JustLooking, and is available at the following locations:

Download JustLooking-3.3.3.dmg now (HTTP)

Download JustLooking-3.3.3.dmg now (BitTorrent – TPB)


Welcome to JustLooking, an image viewing program for Mac OS X. JustLooking is designed to be used instead of the “Preview” application on your computer for browsing most image file formats. In particular, it has the following differences:

  • It focuses on files and directories instead of lists of files. Thus, once you load a file, you can easily navigate through all other files in the same directory.
  • It displays images at their native resolution instead of interpreting DPI information stored in the image meta-data. While images are printed at the maximum resolution possible, on screen they are displayed pixel-by-pixel.
  • Being designed more for viewing of Images, it properly shows animated GIF files.
  • The entire program can easily be manipulated and powered by simple keystrokes for a quick and pleasant viewing experience.
  • There is support for printing, image resizing, saving to a few key image formats, and displaying of all image info.

Version 3.3.3 contains translations for English, Catalan, Dutch, French, Italian, Spanish, Slovenian, Polish, Brasilian Portuguese, Chinese (Simplified), Korean, German, Finnish, Slovakian, Turkish, Croatian, Romanian, Arabic, and Portugal Portuguese.

Requirements and Installation

Running JustLooking is quite simple, and the only requirements are:

  • Mac OS X 10.4 or greater (both Tiger and Leopard work fine)
  • 256MB RAM
  • 8 MB free disk space

JustLooking is installed on any new machine by simply dragging it into the Applications folder.


JustLooking was designed, written, and partially localised (French, Italian, German, Spanish, and some Chinese) by Marc Wandschneider here in Beijing over a couple of casual months. I sat down to write it as a replacement for Preview, as I found the latter to rarely operate in a way that I wanted it to. I tend to keep directories full of images, whether they be traveling, family, or junk I collect from the Intarwebs.

Finder and Preview rarely let me select and view more than a couple hundred of images at a time, and I have large numbers of folders with more files than that.

  • German – Stefanie Schau

  • Portuguese (Brasilian) – Helvécio Mafra
  • Dutch / Flemish – Olaf de Vries
  • Slovenian – Miha Rehar
  • Polish – Tymon Kokoszka
  • Chinese (Simplified) – Jack Zhong

Simple Crop feature would make you a saint! ;-)
Posted By: Christian Oct 30, 2008 05:00:51
Hi Marc!
Thanx a lot for this incredibly simple and good app that beats most of its costy competitors.
Actually, my 75 year old mother is using it without a problem, but she'd like to find a Crop feature as simple as what is built in her Nikon L18, and I can't believe it, but noone has ever made an app that way: cropping based on what you see!
You get what I mean? Simply zooming in and moving around until you see what you want and pressing the button Crop (without bothering about pixel numbers or proportions - basically it would be the same proportion as the original).
Thanx anyway, and may the light be with you! :-)

Not Quit on Close

Hey Kalun,

No, right now JustLooking is kind of a simple one-window quick browsing application. There have been some requests for allowing multiple windows to be open at the same time, and I'll take a look at that, but that would be a 4.0 feature for sure, as it would require re-organising a bunch of the Controller classes.

Wrong Language
Posted By: marcwan Sep 20, 2009 04:37:43
If JustLooking comes up in a language that isn't English, that means this language is set higher in the list of preferred languages in System Preferences.

Go to System Preferences / International / Language, and make sure English (or whatever language you speak) is at the top. If OS X can't find a translation for the language at the top, it just goes down the list until it find something that the app DOES have.
Snow Leopard
Posted By: marcwan Sep 20, 2009 04:39:49
Yep, works great. I've got a snow leopard machine here and use JustLooking every day on it. Slide Show, everything, seems fine. Don't have a remote handy, so I haven't tried that out yet.

Snow Leopard Memory leaking
Posted By: marcwan Oct 02, 2009 04:51:58
Is anybody else seeing Snow Leopard memory leaks? What type of photos are these? I've been looking at high resolution JPGs from a digital camera on my Snow Leopard laptop, and haven't been seeing any leaking at all.

What sort of machines are people seeing these leaks on? Any details would be appreciated.

Posted By: marcwan Nov 04, 2009 04:11:50
That's a good idea. I've been worried about what to do with TPB's uncertain future.

Thanks for the suggestion!

I'd love to help you out with a website for APP and a GUI also.
p.s. I can translate it to Georgian
