First of all it sounds like a review of the User's Manual that came with the 7D is in order.
You could change the "quality" setting, but that would only defeat the purpose of having the 7D.
Is it a "post processing" issue if you are shooting in RAW. Not knowing what software you are using, my only other suggestion would be to maybe "resize" in Microsoft Office Picture Manager if your computer is using Windows and has this program.
I am certain some other's will chime in here too!
Sorry I'm really not much help, but you probably need to provide some more information. i.e, Computer Operating System, Photo software, shooting mode, etc., etc.
