can one disallow attachments in group emails?  I am concerned about folks sending photos to group members which will fill up our drive allotment.

I think you have two options:

1th:

You can use the feature in the google groups settings:

I tested an this feature sucks...

1 - Admins or group admin can bypass the rule

2 - You just deactivate the attachment button, but the insert image still available:

I believe the second option is the best.

You just need to create an attachment compliance rule:

Go to  Admin > Apps > Google Workspace > Gmail > Compliace > Attachment Compliance:

Create a new rule. 

1 - Chose emails messages will effect, 

Inboud (external receiving)
Outbound(external sending)
internal - sending
internal - receiving

This part is up to you, you can chose as you like.

2 - Chose the expressions, which will be all types of attachments:



Now on the step 3, you will decide what to do.
I can reject messages or which is my suggestion, to modify the message:



After chose to modify, its important to chose this option to modify:


And for last, you just need to choose to show options:



And choose to only affect Groups:



You just need to set a name at the top for this rule and then click in save:
This are the results:
Sending an attachment to the group:



Sending an image attached to the body of the message to the group:



Sending a mesage directly to a user is not affected as expected:

Hope it helps!
