[FEATURE] Passing image in non-interactive mode like codex's -i or --image

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

This is very helpful when calling programmatically!

Proposed Solution

Implementation similar to codex feature of image params would be greatly helpful!

Paste images directly into the composer (Ctrl+V / Cmd+V) to attach them to your prompt. You can also attach files via the CLI using -i/--image (comma‑separated):

codex -i screenshot.png "Explain this error"
codex --image img1.png,img2.jpg "Summarize these diagrams"
