Off the top of my head...
$ for f in *.jpg; do; mv $f `echo $f | sed 's/ //g'`; done

(Be careful about the back (single) quotes and the forward single quotes.

BTW, when I write little shell ditties like this, I usually starft with:

$ for f in *.jpg; do; echo mv $f `echo $f | sed 's/ //g'`; done

(Notice the "echo" command conveniently placed to avoid actually doing
anything.)

Also, I usually try the command on a _copy_ of my original directory
(cp -a old_dir new_dir) first, just in case...
