[Plugin: Media File Sizes] Suggestion for performance

Hi,

first of all thanks for this very handy plugin – I would have expected something like that being core of WP, but very cool somebody took care of it 🙂

However, one suggestion regarding performance: Maybe you can add a check around the whole code whether a user is on the admin site…so for “normal” visitors there is no need to register all your actions.

if(is_admin()) {
  // your whole plugin code
}

Not sure, if that makes a big difference, but maybe for sites used heavily it does…
