You have to have all the frames, 57 in your case, as one png. I dont think just putting them altogether will work, they need to be in what is called a panorama image. Do that in photoshop or infaview or similar program. Then take it to DX and make it an object. Under states/animation tab put in number of frames eg 57 and then the frames per ms, trial and error what looks best. Remember to have "loop" checked of otherwise animation will stop straight away. Occassionaly Ive found that although you may have 57 frames sometimes you may have to enter less,,eg 55 or 56,, or more, 58 59. Dont know why. Anyway I hope Ive helped a little, good luck.
