creating a mosaic

Hello.
This might be not a IRAF specific question, but I thought of asking anyway ( maybe it can be done through iraf ).
I have many fits images, from the same patch of the sky, obtained with the same instrument. The astrometry has been done on them. I need to construct a mosaic out of them ( I just temporarily need to see the big picture ). I though of loading the images in ds9 as mosaic segment will do the trick but it this does not seem to work..
I've tried with ds9 from the terminal, both
"ds9 -mosaic [wcs] *.fits"
and
"ds9 -smosaic [wcs] *.fits"
Both do not seem to work, and I get different results ( don't really understand the difference between the two tasks ].
So my question is, is there any quick & dirty way of creating a mosaic? It does not seem to be perfect, close enough will do. Which iraf tast should I explore for this?
Thanks in advance!

See the IMCOMBINE task (w/ parameter offsets=wcs) and help page.
