Single-click original preview in the composer rail and chat history; remove control inside the thumbnail, revealed on hover/focus (always on touch); hidden-scrollbar rail overflow paged by edge arrows with wheel panning and end-reveal on add; image-intake rejections and prompt failures announce as a transient top-center toast instead of inline strips. The attachment atoms move to a new zero-cordis package @deepseek-ai/dsh-client-ui-attachment (rail, message gallery, lightbox), seeded as a platform module; the toast is a ui-primitives atom. Strings arrive as label props bridged from the conversation dictionary.

English | 中文
Pure React attachment atoms (zero cordis): the composer draft-image rail (AttachmentRail), the chat-history image gallery (MessageImage/ImageGallery), and the original-image lightbox (ImageLightbox). Every string arrives through label props resolved by the owning plugin's own locale namespace, and nothing here reads application state; @deepseek-ai/dsh-client-ui-conversation is the current consumer, bridging its conversation dictionary through its image-labels module.
Attachment rail
AttachmentRail renders pending draft images as fixed 64px thumbnails (16px radius) in one horizontally scrolling row whose scrollbar stays hidden. Overflow is announced by circular edge arrows instead: each pages one viewport (minus one card of context, floored at 200px) with smooth scrolling, and arrow visibility is recomputed from scroll geometry on scroll, item-count changes, and window resizes. A vertical wheel pans the rail horizontally with per-tick travel clamped to 60px, while trackpad horizontal pans keep native scrolling. A newly added item is revealed at the rail's end; removal keeps the scroll position. Each thumbnail opens its original through onOpen on a single click, and its remove control sits inside the card's top-right corner, hidden until the card is hovered or the control keyboard-focused; coarse-pointer (touch) surfaces show it permanently because they have no hover. The owner decides mounting and renders the rail only while items exist.
Message images and the lightbox
MessageImage renders one durable history image bounded to 240px on its longer edge, loading a session-authorized URL through the owner's ImageLoader; a failed load renders an explicit retry control, and a settled load answers a single click by opening ImageLightbox (clicks during loading are ignored). ImageGallery wraps a message's images in one aligned flex group (end for user messages, start for assistant messages) and renders nothing for an empty list. ImageLightbox is a document-level modal preview that closes on Escape, a backdrop press, or its close control, and restores focus to its opener on unmount.
Model Experience
None, as the package renders pure React atoms in the browser; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Images only — non-image files have no rail card or history renderer yet; DeepSeek Chat-style file cards and upload-progress states wait until the composer accepts non-image attachments.
- No zoom or download in the lightbox — the preview renders the original at fit-to-viewport size only.
