Image.....Morphing?

Hey all I am very new to flash, and need some help with something if it isnt to much to ask for. I have been reading some tuts about shape tweening and letter tweening that basically will morph into another shape, or letter or whatnot. But my question would be this, I have tried it everyway i can think of, to take 2 images, and make them morph from image, slowly to another image…and seems like I cannot figure out how to do it, I just get a blank screen…any help oh masters of flash? :slight_smile:
