This is something you'll definitely find useful if you're making a video blog, doing a corporate presentation or educational documentary, or if you're creating a news scene. Objects like TVs and computers that can display video can now also display still images in Moviestorm 1.3.
Click on the object in the Director's View, select Change Image, and then just pick your image. You get a handy little indicator on the timeline when the image changes, so you can easily get your timings spot on. And, of course, you can mix and match video footage and images.
