dsh-bridge-preview

When you pair a text-only model (such as deepseek-v4-flash) with dsh-tool-vision image bridge, every pasted image is bridged into an exported to: text hint. The conversation shows only words; the original picture is invisible, and you end up hunting through a file manager just to see what you sent. dsh-bridge-preview solves exactly that: at the display layer it detects the image path inside the hint and renders an inline thumbnail directly in the user bubble, with a click-to-enlarge experience, while the model-facing prompt text, inspect_image calls, and log output remain completely untouched.

The plugin is purely additive. It never mutates persisted messages, never touches the slot system, and never alters any model request. New messages get an instant preview via a MutationObserver; older messages are back-filled automatically, backed by a 2-second fallback scan so nothing is missed. If an image fails to load, the thumbnail silently removes itself without breaking the conversation structure. On the server side a single same-origin read-only loopback route serves images from the bridge export directory, guarded by a localhost restriction, an extension allow-list, a 20 MB cap, and directory-traversal protection.

If you rely on dsh-tool-vision image bridge in bridgeTextOnly mode and want to see a thumbnail in the chat instead of digging through folders, this plugin is built for you.
