Scalosaurus

Resize embedded images the way you'd expect — by dragging them.

Scalosaurus puts real resize handles on your embedded images, right inside the editor. Grab a corner, drag to the size you want, and the new dimensions are written straight back into the wikilink — no more typing |300 by hand and eyeballing the result. Drift near your note's text column and the image snaps to full width, so the size that matters most is one confident drag away.

Sister plugin of Linkosaurus. Works in both Live Preview and Reading Mode, and only ever touches internal ![[image.png]] embeds.

Highlights

• Drag to resize, wherever you edit. Handles appear on hover or tap, in both Live Preview and Reading Mode.
• Proportions stay intact. A locked aspect ratio writes a clean |width and lets Obsidian keep the height; hold Shift — even mid-drag — to size freely as |width x height.
• Magnetic snap to your column. Near the text-column edge the drag snaps (with a guide line) and writes a responsive |100% token that keeps tracking the column as the window, theme, or line width changes.
• Writes once, cleanly. The link updates on release: a single undo step, no flicker, and it targets the exact image you dragged — never a filename guess — so the same image embedded twice resizes independently.
• Stays out of your way. Escape cancels a drag; double-click a handle to clear the size and reset.

Good to know

• Only vault wikilink embeds (![[...]]) are handled — not ![](https://raw.githubusercontent.com/polygonhunter/scalosaurus/HEAD/url) or remote images.
• The responsive |100% (or |fit) token is a Scalosaurus convention. Without the plugin, Obsidian shows the image at its natural size, and some caption plugins render the token as a caption. Prefer fixed pixels? Switch Snapped size format in settings.
• Transcluded images (from ![[Other note]]) are left alone — their link lives in that other file.
• On Obsidian 1.12+, the built-in corner-drag and Scalosaurus coexist; the plugin's handles take precedence where they appear.

Development

npm install
npm run dev    # watch build straight into test-vault/.obsidian/plugins/scalosaurus
npm test       # unit tests (parser, drag reducer, token locator)
npm run build  # typecheck + production build (main.js at repo root)

Open test-vault/ in Obsidian (with the community plugin hot-reload for live reloading). It has demo notes for duplicates, callouts/tables, transclusions and edge cases; docs/findings.md tracks the empirical M0 verification gates.
