Slideshow on axion digital photo frame. i am trying to play a slideshow from a memory stick, but

Question

i am trying to play a slideshow from a memory stick, but it will not play the photos in the order I have stored them -it keeps shuffling the slide show which I had ordered to play along with a particular song. is there a way to make the frame play the slideshow or pictures in the order I saved them? how does it determine which picture to play in what order? thanks! (i have 7 of these to do and have spent 3 days trying to fix this problem) also can you save an mp3 file to the frame itself?
