Pictures are not showing up in Messages on Macbook Pro

Hi,

Lately I noticed that my text and picture messages aren't synching up to iMessage on my MBP.

For example, I sent a photo before the "I need to find this costume lol" text message and it doesn't show up.

Help?

I made the same post before, but accidentally clicked that a reply from another user solved my issue. Just as an update: I reset my network settings, I sign out of my apple account, I toggled with the iMessage button, I restarted both my MBP and iPhone 6.
