We aren't going to be able to give you an "out of the box" solution: this is not a trivial process in any way, shape or form.
The problem is that Bimap, JPG, PNG, etc. files are raster graphics: they store a fixed array of pixels in various shades of red, green and blue (or hue, lightness and shade - whatever) while SVG files are vector graphics - which means they store images as "draw line from (x1, y1) to (x2, y2)" and "draw an arc here" commands.
And the two are not compatible.
It is possible to do - the process is called "vectorisation" - but the results are unlikely to be perfect, and if you are talking about a natural world object (like a photo of a face) it's very, very unlikely to work without some considerable effort on your part.
Certainly, there is no simple "plug in code" that I know of that will let you do that: but there is this approach which looks interesting: http://asserttrue.blogspot.co.uk/2010/01/fast-conversion-of-bitmaps-to-svg.html#
I don't think you are going to find this a simple task: be prepared to put some significant effort into this!
