Uh, the way you would for any other pic? Just convert it into a JPG, GIF, or something else first.

There is no powerpoint picture, this is not a picture format. You should try to copy/paste the picture you want from your powerpoint document to a picture software such as Paint, and there you should be able to save it as a JPG.
BTW, "help me??" is not a good title for a topic like that. You've got to explain your problem in the title if you want more people to read it.

Draw in a real picture editor such as Paint, Photoshop or Paint shop pro. Or, you can also try to "print screen" your powerpoint picture and paste it in a picture editor.
