Newbie here!

I am trying to pull a file into Illustrator, Live Trace and then save as an SVG file, but everytime I do, all I get is the surrounding box and no image. The only time it's worked a little differently was to cut out the bounding box and little diagonal lines in each of the corners. Any advice or help would be appreciated. I have SO MANY IMAGES that I'd love to cut, but until I figure out how to do it, I'm stuck in the water! Thanks in advance for the help! I know there is some wonderful smart person on here who knows what I'm doing wrong.
Thanks,
Michele
