Image Orientation in Bridge View

You could always just turn off auto rotation in the camera.

Not that I know of, but you could run the following script that will select all files in the selected folder that need to be rotated.

The script need to be saved as plain text with a .jsx extension. The correct folder can be opened by going to Bridge preferences - Startup Scripts and clicking the "Reveal my Startup Scripts" button.

#target bridge;
 if( BridgeTalk.appName == "bridge" ) {  
rotatedFiles = MenuElement.create( "command", "Rotated Files", "at the end of Tools");
}
rotatedFiles.onSelect = function () { 
var sels = app.document.visibleThumbnails;
var rotated = new Array();
for (var a in sels){if(sels.rotation != 0) rotated.push(sels);}
app.document.deselectAll();
for(var z in turned) { app.document.select(rotated);}
};

Once the file is saved close and restart Bridge and accept the new script.

To use: Tools - Rotated Files

It should then select all files that need to be rotated.
