I have a Samsung S7 and I keep having those emojis in my gallery!

[Android Central Question]

I have a Samsung S7 and I keep having those emojis in my gallery (from the Orca file)as soon as I use the Messenger App. I did create a ".nomedia" file but nothing happened other than giving me a new message ".nomedia file found - Items in internal storage can't be shown because of a .nomedia file in this album. Delete this file to view your items". What do I do now?? I'm so tired of those 100's of emojis! They make my phone freeze...Thanks.
