I've installed the Edge Animate command extra for Fireworks and have a series of png's each in it's own state - set to 'include when exporting.'
When I use this extra (using any of the export options) either only one png is created or none are. All the other relevant html, edge and js files are created. Even an image folder is created, but no series of images. Therefore, my animation isn't exactly an animation with only one image.
