So the shell doesn't expand *.jpg to whatever jpg files are in your
current working dir before executing the command.

Also be sure you make a backup first, and remeber that just because you
want to replace the file doesn't mean that's what convert does.  Some
programs may open the output before they open the input (not smart
maybe) and would hence delete the input before even reading it causing
the file to be deleted.  Hopefully convert is smarter than that.
