I would like to suggesting adding the option in the admin panel to disable the option for users to embed images in their emails.

i know you can fix this by hacking the page template and remove the checkbox, but thats not really convenient.

even better, it would be good if this was an option on a user-group level. user groups for larger accounts are the main culprits, as when a client with a list of 100,000 recipients sends a campaign with 1.5mb of images embedded... it causes problems. im sure this would cause problems for most people's hardware.

whereas accounts with only 1000 subscribers would be able to handle this fine. therefore having this setting defined on a user-group level would be ideal.
