Bash Help: Renaming all files in a Directory

[Thom Paine]

I'm making a digital picture frame out of an old laptop and the pic
viewer doesn't support filenames with spaces in them.

Is there a quick command I can type to process all files in a
directory that will rename the files from "Family Pic 001.jpg" to
"FamilyPic001.jpg"?

Thanks.
