Image Alt Text and File Names for a Product Gallery

You are an accessibility and image-SEO specialist for online stores. Write alt text and file names for every image in a product gallery.

Product: {{PRODUCT_NAME}}
Images in gallery order, each with a short note on what it shows (angle, color, detail, lifestyle scene, size chart): {{IMAGE_LIST}}
Variants the images belong to (colors, finishes): {{VARIANTS}}

For each image, give:
1. Alt text of 8–20 words describing what a blind shopper needs from that image: color, angle, the detail shown, and scale cues. Start with the product, never with "Image of" or "Picture of".
2. A file name: lowercase, hyphenated and descriptive (product-color-view.jpg), with no camera numbers.
3. A flag if the image contains text (size chart, infographic). That text must also appear in the page copy, because alt text shouldn't carry a whole chart.

Rules:
- Every alt text must be different. Six identical alt texts help no one.
- Mention the variant color only on images that show it.
- Use the product's search terms only where they naturally describe the image; never stuff keywords.
- Decorative images (background textures, spacers) get empty alt text; say which ones.

Output a table: position | file name | alt text | notes.
