Personalized-product shops receive unusable photos: blurry, backlit, too
small to print. The problem is discovered after the order, and costs an email
exchange, a refund, or an unhappy customer.

Fotalyze scores the photo the moment the customer picks it, and tells them
clearly what’s wrong — before they pay.

The photo never leaves the customer’s device

All the analysis happens in the browser. No image is ever sent to a server,
neither yours nor the plugin’s. There is no third-party service, no account to
create, no outgoing request, no personal data transmitted.

Warns, never blocks

By default, the plugin warns the customer and lets them order anyway. This is
deliberate: no automated tool judges a photo as well as a human does, and
rejecting a good photo costs a sale.

Blocking the add-to-cart button exists as a Pro feature, so it’s a deliberate
choice you make once the thresholds have been proven on your own orders — not
something a fresh install can do by accident.

What is measured

Sharpness — Laplacian variance, to catch motion blur or missed focus.
Exposure — overexposed or overly dark areas, where detail is permanently lost.
Backlight — a subject noticeably darker than its background. Warns only.
Resolution — actual image size compared to what your print format requires.
Screenshot detection — recognises files that aren’t photographs at all.

Shop-wide thresholds are adjustable from WooCommerce Fotalyze.

The score stays attached to the order

The verdict the customer saw is recorded on the order line — for free, on
every order. So if a dispute comes up, you know the customer was warned and
ordered anyway.

Free vs. Pro

Free forever:

Photo scoring with every metric above.
Customer-facing warning — never blocks the order.
Shop-wide thresholds.
The score attached to every order line.

Fotalyze Pro adds:

Optional blocking of the add-to-cart button, once you trust your thresholds.
Per-product thresholds — a large-format print can demand a higher
resolution than a small one, without changing the shop-wide default.
A history screen listing every order with a photo score, instead of opening
orders one by one.
