Image too small: the size Google needs

What Google's message means

The main image is below Google's minimum: 100 × 100 px for most products, 250 × 250 px for apparel — and anything under about 800 px is also downgraded in results.

Below the minimum the product is disapproved; small-but-allowed images lose placement to competitors with sharper ones.

The fix in Shopify

1. Products → the product → Media: upload the original photo at least 800 × 800 px (1200 px or more for zoom), the product filling most of the frame, and drag it first. Save.
2. If the feed comes from a third-party feed app, its image setting must send the original file, not a size-suffixed thumbnail (_100x100).
3. Google re-checks the product at its next crawl (usually within a day); the next RevenueCue scan confirms it's clear.

The fix in WooCommerce

1. Products → the product → Product image → Set product image: upload the original photo at least 800 × 800 px (1200 px or more for zoom). Update.
2. If a feed plugin is used instead of Google for WooCommerce, set its image size to ‘Full’ / original, not ‘thumbnail’ or ‘woocommerce_thumbnail’.
3. Google re-checks the product at its next crawl (usually within a day); the next RevenueCue scan confirms it's clear.

What it costs while it's down

Every product Google flags this way is out of Google Shopping — no ads, no free listing — until it's fixed. Its listed price is what isn't being shown; a free scan names each product and adds up the listed value at stake.
