A successful handoff makes the approved choice easy to identify and difficult to misuse. Designers need editable context and crop guidance. Developers need predictable files, dimensions and accessibility intent. Both need to know which source and approval the asset represents.
Separate source, master and delivery derivatives
Provide an untouched source archive, an approved editable master and clearly named output derivatives. Do not ask a developer to infer the master from a folder of experiments. Include checksums or stable IDs when assets move through several systems.
Use durable formats appropriate to the work and document any dependency needed to reopen an editable file. Library of Congress format guidance highlights sustainability and disclosure factors that are useful when planning long-term access.Library of Congress format guidance ↗
Give designers crop and composition intent
Show approved wide, square and portrait examples, safe areas, focal point and allowed reframing. Identify protected elements that cannot be retouched or obscured. A flexible master still needs boundaries.
Include colour profile, transparency behaviour and any overlay assumptions. Link the asset to the current component or campaign template instead of relying on a screenshot with unknown dimensions.
Give developers implementation-ready information
List intrinsic dimensions, formats, expected rendered sizes, fallback and responsive variants. W3C responsive image use cases distinguish resolution switching from art direction; mark when a crop is a different composition rather than merely a smaller file.W3C responsive image use cases ↗
State whether the image is decorative, conveys content or acts as a control. Supply purpose-led alternative text or the information needed to write it. W3C’s decision tree provides a practical route for choosing the right text alternative.W3C image guidance ↗
Attach approval, rights and alteration notes
Identify the approved version, reviewer, date, placements and limitations. Include source rights, consent scope and required credit. IPTC fields can carry useful rights and descriptive metadata, but confirm that the delivery pipeline preserves them.IPTC Photo Metadata Standard ↗
Walk through one real implementation with the receiving team. Correct missing assumptions in the package, then freeze the release manifest. A good handoff ends with shared understanding, not simply a download link.
Make the release manifest the front door
The manifest should list asset ID, filename, purpose, dimensions, format, colour profile, source master, approval, rights note and checksum. Add focal point or crop behaviour for responsive images. Link to the editable file and production record without making either the only explanation.
Version the manifest with the package. If one derivative is corrected, update its checksum and release status without silently replacing the earlier delivery. The receiving team can then reconcile what they implemented with what the studio currently approves.
Test a real component together
Place the image in a representative desktop and mobile component, then inspect crop, loading behaviour, intrinsic dimensions, contrast with overlays and alternative text. Confirm whether the implementation uses resolution switching or different art-directed crops. Capture the accepted example beside the handoff.
Check failure behaviour too. A missing optional image should not remove essential information, and a slow image should not cause unstable layout. Developers can surface these constraints early when the handoff includes purpose instead of only pixels.
Define the route for later changes
Tell recipients which adaptations they may make directly and which need new approval. Resizing an approved derivative may be routine; changing a person, product, embedded copy or synthetic setting can reopen editorial, rights and QA work.
Provide a contact role or issue channel rather than a personal promise that may disappear. Ask change requests to include asset ID, current placement, desired outcome and deadline. This preserves context and keeps unofficial derivatives from becoming hidden new masters.
A practical decision table
| Recipient | Needs | Proof |
|---|---|---|
| Designer | Master, crops, safe areas, colour | Placed layout examples |
| Developer | Variants, dimensions, alt intent | Responsive component test |
| Producer | Approval, rights, asset IDs | Release manifest |
Release checklist
- Identify the approved master
- Archive the source separately
- Name derivatives consistently
- Document focal point
- Provide crop examples
- State colour and transparency
- List responsive sizes
- Supply alt-text intent
- Include rights and credits
- Test one implementation together
Common questions
Should developers receive the editable master?
They need access when future derivatives are expected, but production code should reference optimised approved outputs.
Can metadata replace a handoff note?
No. Metadata helps assets travel, while the handoff explains placement, decisions and responsibilities.
