Client-side image handling - preview generation, Canvas API resizing, compression, EXIF orientation, format conversion, memory management with object URL cleanup.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Image Handling Patterns > **Quick Guide:** Two different jobs with two different tools. Displaying an image means > `URL.createObjectURL()` and revoking it afterwards — the browser already applies EXIF rotation, so > rotating manually rotates twice. Processing an image means Canvas: clamp to 4096px, scale in > multiple passes for reductions past 50%, fill white before writing JPEG, and prefer the async > `toBlob()` over `toDataURL()`. **Detailed Resources:** - [examples/core.md](examples/core.md) — the shared `loadImage` helper, preview hook and component, dimension extraction and validation, EXIF parsing, gallery state - [examples/preview.md](examples/preview.md) — parallel thumbnail sets, gallery grid - [examples/canvas.md](examples/canvas.md) — the resize pipeline, target-size compression, cropping, watermarks, filters - [reference.md](reference.md) — format and strategy selection, constants, method comparison, EXIF values, browser support --- ## Which path applies The two paths disagree about EXIF, which is where most of the bugs are. - **Displaying to the user** — object URL straight into `<img>`, revoked when it is replaced or …

How to install
mdr add agents-inc/skills/web-files-image-handling@sha256:32048a17fed7808eThe line at the top of this page pins the label git:20260906.5c10830, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
