Implementing img expressions feature,

[hgftrdw45ud67is8o89]

i see some bots* in chub.ai has those expressions file.
I think it would be cool if it could be implemented.

Currently I can only think of regex or key word searching then use picture accordingly. As I had never used other framework/app that has the expression features. anyone has ideas?

It seems like a decently easy feature that mainly messes with ui not the llm.
