Why pack_product.py Renders Both a 1280×720 Cover and a 600×600 Thumbnail

Описание и применение

Скрипт pack_product.py генерирует два изображения: 1280×720 для главного изображения и 600×600 для миниатюры, чтобы удовлетворить требования разных площадок.

Задача

Uploads were rejected because the packaging script produced a single image that failed to meet the differing aspect‑ratio requirements of marketplace listings and grid thumbnails.

Результат

The dual‑canvas approach eliminates upload rejections and ensures that both hero and thumbnail images display correctly across all marketplace surfaces.

Рабочий процесс

• 1. Run python pack_product.py <product_name> "Product Title" "Subtitle" <count>
• 2. The script zips product files into <product-name>.zip
• 3. Pillow renders a 1280×720 cover image as <product-name>-cover.jpg
• 4. Pillow renders a 600×600 thumbnail as <product-name>-thumb.jpg
• 5. All three files are placed in the _system folder (or specified via --dir or PACK_ROOT).

Доказательства

I built 39 products on a 1 vCPU, 2 GB RAM server before I understood why my uploads kept getting rejected.

Источник

pack_product.py renders both, every pack, with no flag to turn either off.

Источник

The cover is the hero image. It is what the buyer sees first on a product page or a marketplace listing, and it is the one they judge in roughly two seconds.

Источник

The thumbnail is the survival test. It shows up in grids, search results, category rows, and recommendation strips, often at 100px or less, often cropped to a square.
