Is there a reason for the 600 frame limit in the Screen Capture module? (It looks easy enough to change in [ScreenCapture.py](http://ScreenCapture.py), I was just wondering if there was a reason for the limit.)

Thanks!

The only reason for a maximum limit is the slider widget. If the max value of the slider is too high then it is very hard to adjust the slider in small steps. You could add a maximum number of images spinbox in the Advanced section and send a pull request.

Done, just submitted pull request. It turned out to be more straightforward than I thought it would be.

@hherhold contributed the changes and they just got integrated in [r26507](http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=26507) . It means, they will be available in tomorrow nightly build available at [Download 3D Slicer | 3D Slicer](http://download.slicer.org/#installers)

Well done 👍
