In your group settings, you could set the Attachments option under Message Formatting to Moderated.? Then you could see how large they are before approving them.
On my groups, I set the Default Sub Settings for attachments to 0 (all attachments are sent as links in emails.)? If someone wants to receive the actual attachments, they can change it to whatever size they're comfortable with.? That won't do anything for existing members, only new ones.? If you don't have too many existing members, you could change it for each of them in their Advanced Preferences.? Otherwise you could post instructions on your group and hopefully most would change it, if needed.
