Description from developer:
“These are files that the default QuickLook plugins doesn’t handle.

QLStephen solves that.”

“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.”

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 :
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
<string>DivX Video File</string>
3. In Terminal.app
touch /Applications/QuickTime\ Player.app
