Drop no longer leaks decideTransfer from the handler. Unsupported dropped MIME types fail at the naming helper instead of pretending to fall back. Co-authored-by: Christian Bager Bach Houmann <christian@bagerbach.com>

📝 WalkthroughWalkthroughChangesThe image intake handler now supports pasted and dropped images in value prompts. It resolves vault files, saves external image bytes, preserves valid dropped filenames, inserts embed links, serializes saves, and shows drag-target feedback. Tests and documentation cover the new behavior. Image transfer support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Drag-and-drop image support is mergeable with owner awareness, but a narrow text-drop case can be interpreted as an image embed, and certain Windows-reserved filename variants may not be handled as intended; the accompanying documentation also needs wording corrections.

The new drop path is reachable only through browser DragEvent listeners here; a repo-wide search finds no command/API entrypoint, inspectable drop state, or deterministic logging that would let obsidian:e2e verify this behavior, leaving only synthetic jsdom coverage. Add a CLI-native seam and automated coverage around it as required for UI-only flows.

When a webview exposes a file-kind DataTransferItem with an empty or unrecognized item.type while data.files contains the same image with a supported File.type, hasFileItems becomes true and this return skips the working FileList fallback. The paste or drop then silently stands down even though a supported image is available; return early only after collecting an image, or scan data.files for entries not already collected.

319-331: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winConsider returning the stem decision from the naming helper instead of re-parsing the filename.
droppedImageNaminginfers the naming strategy by string comparison withclipboardImageFilename, then recovers the stem withslice(0, -(extension.length + 1)). This works only while both helpers derive the extension from the same map and sharenow. A future change to the clipboard filename format would silently produce a wrong stem.A small exported helper in
clipboardImageAttachments.tsthat returns the usable stem ornullwould remove both the comparison and the slice.🤖 Prompt for AI Agents

Document sanitized dropped filenames.
The implementation preserves dropped filenames after sanitization, not necessarily with their exact filesystem spelling.

Gate onDrop on transferMayCarryFiles, like onDragEnterOrOver.
onDrop accepts any drop that reaches the input, including a text-only drag. decideTransfer("drop", ...) then runs collectVaultImages over text/plain. If the dragged text is a vault-relative path to a supported image, the handler calls preventDefault and inserts an embed link instead of the dragged text. The user loses the intended text drop.
onDragEnterOrOver already requires transferMayCarryFiles(data). Apply the same condition in onDrop.
🐛 Proposed fix
const onDrop = (event: DragEvent) => {
clearDropTarget();
if (composing) return;
const data = event.dataTransfer;
if (!data) return;
+ if (!transferMayCarryFiles(data)) return;
const now = new Date();
acceptDecision("drop", event, decideTransfer("drop", data, app, now), now);

Describe vault-image reuse instead of saying every image is saved.
The handler reuses images that are already vault files and saves only byte-based images.

Closes #1700.
Why
Content prompts already accept clipboard image paste (#1484 / PR #1492). Dragging an image from a file manager onto those prompts still did nothing. Paste cannot be reused as-is: a file-manager drag includes the path as
text/plain, so paste's text-wins rule would insert a filesystem path and never save the image.Scope
attachImagePasteHandlernow accepts drop as well as paste. Call sites inGenericInputPrompt,GenericWideInputPrompt, andOnePageInputModalare unchanged.options.imagePasteremains the single gate.decideTransferparses aDataTransferintoPromptImage(new bytes, or an already-vaultedTFile). Paste still stands down whentext/plainis non-empty. Drop prefers image files. Dropped files keep a sanitized original name. Paste still usesClipboard image {timestamp}. A vault-relativetext/plainpath that resolves to a supported image embeds that file and does not copy it.saveImageBytesToVaultis the write sink.saveClipboardImageToVaultkeeps its four-argument signature for Capture{{CLIPBOARD}}.Docs in
FormatSyntax.mdandQuickAddAPI.mdmention drag-and-drop and the two precedence rules.Tradeoffs
The public option stays
imagePasteso scripts and the formatter do not grow a second flag that would have to stay in sync.Obsidian's private
dragManageris not used. A Files-plugin drag embeds without copying only whentext/plainis a vault-relative image path. Other internal drags may save a duplicate attachment.The drop target is the input, not the modal, so a one-page form does not have to guess which field should receive the embed.
Blast Radius

{{VALUE}}prompts, one-page free-text fields, andquickAddApi.inputPrompt/wideInputPromptwithimagePasteenabled. Path, filename, number, and slider prompts stay text-only. Capture{{CLIPBOARD}}image fallback is unchanged. No settings or data.json migration. Cancelling after a drop leaves the attachment, same as paste and the Obsidian editor.Verification
