Unable to text images to android users, cannot find an option to enable MMS

I have a friend that uses Android, her and I text cat pictures to each other all day. But today I started getting an error while trying to send any to her. I can send messages without images fine.

I looked in message settings for an option to enable MMS but do not see anything. I searched settings as well.

I get this when I search, but touching it brings me to messages settings and no mms options.
