Dragging an image does not restore a workflow: verify that metadata survived

Symptoms and scope

A displayed result, screenshot or resaved image may not contain recoverable workflow data. This alone does not indicate a broken import function.

Error fragments for search; IDs, values and filenames may vary:

No workflow found
workflow metadata

Source-supported context

Official examples describe importing images that contain workflow JSON metadata. VideoHelperSuite also has an optional workflow-metadata setting; a generated picture is not proof that its current file retains the graph. Source 1 Source 2 Source 3

Cases to distinguish

1. The saved file is a thumbnail, screenshot or platform-recompressed image.

2. The author omitted metadata or disabled its export.

3. Metadata exists but its format, nodes or frontend requirements are outside the current parser's support.

Diagnostic sequence

The sequence below is an editorial procedure based on the cited context, not a diagnosis already confirmed for your environment.

Step 1. Prefer the author's original attachment or standalone workflow JSON rather than a displayed thumbnail.

Step 2. Inspect metadata on a separate copy. This site's JSON-only tool cannot extract image metadata, so its rejection does not prove metadata is absent.

Step 3. Use an available original JSON. If only pixels remain, ask the author for the graph; a reconstruction from appearance is not exact recovery.

Step 4. After import, check missing nodes, models and versions as separate dependency steps.

Completion check

An original parseable graph restores plausible nodes and connections. Execution still depends on its environment and resources.

Limitations and cautions

Metadata may expose prompts, paths and other information. Inspect it before public sharing; pixels alone cannot guarantee recovery of the original seed and full settings.
