越境EC向け GPT Image 2 活用法：1枚のヒーロー画像を8言語に展開する

A 1:1 square e-commerce hero image. White stainless steel water
bottle on a beige linen tablecloth, soft window light from the
left at 45 degrees, premium minimalist product photography style.

Top-left red rectangular badge reads "50% OFF",
top-right gold circular badge reads "24h Hot/Cold",
below the bottle bold black headline reads "Daily Commute Companion",
bottom-center small text reads "Tap to Shop".

Shot on Sony A7R IV, clean composition, no other objects in frame.

In this image, replace the text only:
- Top-left badge reads "50%引き" instead of "50% OFF"
- Top-right badge reads "24時間保温保冷" instead of "24h Hot/Cold"
- Headline reads "毎日の通勤の相棒" instead of "Daily Commute Companion"
- Bottom text reads "今すぐ購入" instead of "Tap to Shop"

Keep the bottle, lighting, background, layout, and badge colors
exactly the same. Only the text content changes.

In this image, replace the text only:
- Top-left badge: "50% 할인"
- Top-right badge: "24시간 보온/보냉"
- Headline: "매일의 통근 동반자"
- Bottom text: "지금 구매하기"

Keep all other elements identical.

In this image, replace the text only with the Arabic equivalents,
applying right-to-left layout to the badges and headline:
- Top-right badge: "خصم 50%"
- Top-left badge: "ساخن/بارد لمدة 24 ساعة"
- Headline: "رفيقك اليومي للتنقل"
- Bottom text: "انقر للشراء"

Mirror the badge positions for RTL convention. Keep bottle,
lighting, and background unchanged.

In this image, adjust for the Chinese mainland market:
