The quick answer to your question is no. If you would like to display
raster data (jpeg, tiff) with mapserver then add georeference to those
files (see raster howto).

The slower yes answer :)
Shape files store vector data (co-ordinates, lines, etc),
jpeg, tiff files stores adjecent pixel values.
You may vectorize raster data by
drawing vectors on the raster in a CAD or mapping software.
There are some raster to vector (R2V) which tries to generate
the vector from the raster automaticly, but the result usually
needs 30-70% postprocessing :(

Bye
Zoltan
