Why doesn't changing a WooCommerce product photo change the category tile?

Identify the displayed record

First confirm that the tile is a product category tile, not a product card filtered by category. A category tile normally represents the category record itself; a product card represents an individual product. This distinction determines which media assignment can affect the visible image.

Open the relevant product category record in the WooCommerce administration area and compare its name, slug, and current category thumbnail with the category shown on the storefront. Do not assume that the category attached to the edited product is the same record being displayed: similarly named categories, translated records, or parent and child categories can lead you to the wrong record.

1. Record the product name, its featured photo, the category name shown on the storefront, and the category thumbnail currently assigned to that category record.
2. Use a staging copy, or a temporary category explicitly included in the test storefront listing. Verify the tile links to that exact category record before assigning a distinct image through its thumbnail field. Preserve the original assignment.
3. Confirm the listing points to the edited category record, then refresh it in a separate browsing session and compare the tile with that record.

Trace the separate assignment

The product’s featured image and the category’s Thumbnail are separate assignments. Replacing the featured image changes the product asset; it does not rewrite the category record’s Thumbnail. If the category tile remains unchanged, inspect the category record first, then inspect whether the storefront is displaying another category record or a retained rendered result.

Use the media details to distinguish files by name, dimensions, or visible content. Evidence is stronger when the category record shows the test image but the tile shows a different image, because that separates an assignment problem from a display or refresh problem.

Illustrative exercise

Illustrative exercise: define Asset A as the product “Blue Field Notebook” with featured image “notebook-front.jpg.” Define Asset B as the category record “Stationery” with Thumbnail “stationery-shelf.jpg.” These are two distinguishable assets with independent values before any A/B comparison.

For the test, replace only Asset A with “notebook-back.jpg” and leave Asset B unchanged. A pass for the product-photo test is that the product card changes to “notebook-back.jpg” while the Stationery category tile remains “stationery-shelf.jpg.” A fail for the category diagnosis is claiming the product edit should have changed the tile. Next, assign a visibly different test image to Asset B’s Thumbnail. A pass is that the Stationery tile changes to that test image after the storefront reflects the saved category record.

1. A: edit only the product featured image and observe the product card and category tile separately.
2. B: edit only the category Thumbnail and observe the category tile.
3. Compare which rendered element changed; use that result to choose the next branch.

Acceptance condition

Accept the fix only when the category record being displayed has the intended Thumbnail, the product record has the intended featured image, and each appears in its corresponding storefront location. If the category record is correct but the tile remains old, stop replacing product photos and investigate record identity and rendering or refresh behavior. If the record itself is wrong, correct the category Thumbnail first.
