What's Wrong?

I uploaded a mobile screenshot to a conversation. The system flagged it as exceeding the 2000px dimension limit for multi-image requests. From that point on, every single message I sent returned the same error — the conversation was completely unusable.

There's no way to delete the image or the message containing it, so the entire conversation is permanently bricked. I lost all context from a long, complex session I'd been building up.

Two things need to be fixed:

Let users delete individual messages/images from a conversation so a single bad upload doesn't destroy an entire session.
Handle the error gracefully — skip or resize the problematic image on subsequent turns instead of failing the entire conversation forever.

What Should Happen?

fix this please

Steps to Reproduce

An image in the conversation exceeds the dimension limit for many-image requests (2000px). Start a new session with fewer images.
