Approved.
Contained desktop-only UI feature with strong test coverage, authored and owned by the same team with STRONG author familiarity; the one prior CodeRabbit correctness comment (dropping clipboard files with empty MIME type) is now handled in the current diff via byte-signature detection, and no reviewer or maintainer hold remains open.
- Author wrote 100% of the modified lines and has 21 merged PRs in these paths (familiarity STRONG).
- 👍 on the PR from greptile-apps[bot].
- 5 of the 5 changed files are governed by
products/desktop/AGENT_APPROVALS.md.

Problem
Desktop feedback requires a file picker to attach images. Why: Let users paste screenshots directly into the message.
Changes
Pasted images use the existing upload checks, compression, and two-image limit. Previews open automatically and let users remove images before sending. Text paste still works. A second image paste during processing shows a retry message. The shared validator accepts supported image signatures without MIME metadata and rejects mismatched formats.
This uses the existing feedback route and can ship independently of ticket routing.
Before paste:

After paste:

How did you test this code?
The focused automated tests passed. They cover image uploads and paste, removal, mixed text, image limits, invalid formats, and blocked submission during processing. A browser check confirmed image preview and removal in the rendered feedback form. The browser check also covered paste without MIME metadata. Native OS clipboard testing remains a release check.
Docs update
Updated the Desktop feedback guide with image paste behavior.
