It has been brought to our attention that some plug-ins do not work with OS X 10.6/Snow Leopard.
Since we do not actually develop the plug-ins we list on this site, we cannot investigate each one. Instead we thought we would setup this post to allow for users to comment and allow for discussion on tips and tricks for getting plug-ins to work with 10.6.
So feel free to leave a comment with your experience and especially if you have tips for getting plug-ins to work with Snow Leopard. All comments are moderated, but will be published at least once a day.

The first Quick Look Plugin geared specifically for photographers.
From the plug-in’s website:
“With SneakPeek Photo simply click on the unopened photo file (no matter where it is, even on your card reader) and hit the space bar. Up pops the picture into a large view that immediately gives you the detailed information you need. On the top bar, the much needed basics such as the type of file, its size, f-stop, focal length, color Sfile (sRGB, ProPhoto, etc) even a mini histogram. But there’s much more. Also on this view you’ll see buttons which will give you Exif data, all the camera settings, a Loupe View with high resolution zooms, and a large Histogram to see the blueprint of your shot. If the photo is geotagged, you’ll not only see the coordinates, but a nifty map of where the picture was taken. Plus there’s even a link to a more detailed map online.”
Cost: $10

Preview FITS header+images/spectra directly inside the Finder!
Released: 2009-07-16
http://www.softtenebraslux.com
QLFits allows you to see FITS files right into your Finder, without opening the file! It automatically generates on-the-fly a colorized header, with images and/or spectra below! It even supports multi-extension fits files. Even better, it detects ESO keywords, and build automatic links to the proposal abstract, the file summary, and even the weather conditions!
Features:
• Colorized header.
• Quick summary + Full header
• Automatic detection of ESO keywords
• Links to ESO archive seeing/prog id pages (when possible)
• Support for multi-extensiom FITS files!
• On-the-fly preview of 2D images!
• On-the-fly preview of 1D spectra!
• For 2D images: On-the-fly thumbnail of 1st extension that contains data
• For 1D spectra: On-the-fly thumbnail of the spectrum
• Display of the value of the “OBJECT” header keyword, with large fonts.
Notes: images pixels are scaled linearly (it produces in general better results than linear or logarithmic-zscaling). If no data are present in the FITS, only the header is shown.
Thanks, Cédric!

This may look pretty familiar as I have adapted it from the Matroska Video File “plugin”. After having seen that one I figured you could do it for any file format (at least for Quicktime). So here is one for DIVX.
1. First you need DivX/Perian for .divx support in Quicktime :
http://perian.org/, http://www.divx.com
2. Then you need to add a Uniform Type Identifier in Quicktime Player :
- Edit QuickTime Player.appÂ’s /Contents/info.plist
- Add the following code just before the last 2 tags
<key>UTTypeConformsTo</key>
<array>
<string>public.movie</string>
</array>
<key>UTTypeDescription</key>
<string>DivX Video File</string>
<key>UTTypeIconName</key>
<string>generic</string>
<key>UTTypeIdentifier</key>
<string>com.apple.quicktime.divx</string>
<key>UTTypeReferenceURL</key>
<string>http://www.divx.com/</string>
<key>UTTypeTagSpecification</key>
<dict>
<key>public.filename-extension</key>
<array>
<string>divx</string>

Here is a neat trick that I am sure could be expanded to include even more file types, as submitted by reader Frantz. Thanks, Frantz!
I’ve found a trick allowing me to display Matroska video files in Quicklook without the need of a plugin :
1 / First you need Perian for mkv support in Quicktime : http://perian.org/
2 / Then you need to add a Uniform Type Identifier in Quicktime Player :
- Edit QuickTime Player.app’s /Contents/info.plist
- Add the following code just before the last 2 tags </dict></plist> :
<key>UTExportedTypeDeclarations</key>
<array>
<dict>
<key>UTTypeConformsTo</key>
