Those Macros i painstakingly set up are not needed ! there is a setting in premier that allows it to automatically resize clips to the preset working size, also if you want to make a static image more interesting aplying motion and zoom effects to the images is relatively simple. this is why a video editing application is preferable to applications like nero as the range of options you have will enhance the look of the slideshow and it is relatively simple to alter the tempo of the slideshow by changing individual clip lengths.
