Imagery

Site Imagery

Use this skill whenever a design calls for images — hero/cover backgrounds, feature, gallery, or card images, team photos, product shots — and before every generate_images call.

Workflow

1. Plan all imagery first. While planning a page or theme, list every image it needs: filename, subject, placement, aspect ratio. Generate images BEFORE writing the markup that references them, so markup always points at real files.
2. Pick the destination per image:
   • Theme imagery (part of the theme's design: hero/cover backgrounds in templates or template parts, section background bands): write to <site>/wp-content/themes/<theme-slug>/assets/images/<name>.jpg and reference it in markup as /wp-content/themes/<theme-slug>/assets/images/<name>.jpg.
   • Site-specific content imagery (images inside page/post content: products, team photos, gallery items, feature illustrations): generate to a staging path like <site>/wp-content/uploads/studio-generated/<name>.jpg, then import into the media library and use the attachment:

     wp_cli media import wp-content/uploads/studio-generated/<name>.jpg --porcelain   → <id>
     wp_cli post list --post_type=attachment --post__in=<id> --field=guid             → URL
     

     Use the returned URL as the src and the id in the block attrs (e.g. wp:image {"id":<id>,"sizeSlug":"large"}). Delete the staging file afterwards.
3. Batch aggressively. One generate_images call per page (or per site for small sites) with every image in the images array — generation is concurrent server-side. Never one call per image.
4. Write real alt text. Generated images are content: give every <img> a short, descriptive alt in the markup (what the image shows, for a person who cannot see it). Never leave a spec string or an empty alt on a content image; cover backgrounds keep an empty alt (decorative).
5. Verify. After applying markup, use take_screenshot to confirm the images render, fill their slots, and keep overlaid text legible.

Writing the spec fields

Every image in the images array takes path, subject, pageContext, style, aspectRatio. The call also takes a shared siteContext and imageGrade.

subject — what the image shows

1–3 specific sentences describing ONLY the image itself: what it shows and from what point of view (composition, framing, vantage, mood).

• NEVER ask the image to render text. No words, names, letters, numerals, wordmarks, signage copy, or "hand-lettering of " — in any language. Image models garble glyphs and invent fake scripts. Everything meant to be read is real HTML typography styled by the theme. Prefer scenes whose focal subject carries no lettering at all: the model completes any prominent sign, storefront, menu board, or screen with garbled fake text. When a text-bearing surface is unavoidable, describe it as bare (clear glass, an unmarked awning, a blank board) or keep it distant, oblique, or out of focus. Never write words for signage into the subject even to negate them — naming lettering plants it.
• Describe content and composition, NOT photographic grade. The site-wide imageGrade is applied to every image; do not restate or contradict it per image (no "black and white", "golden hour", "35mm grain" in subjects) — per-image grading makes adjacent images clash.
• Make sibling images in the same section describe distinct subjects so they don't read alike.
• For cover backgrounds with overlaid copy, keep the focal subject off-center with calm, low-detail areas so the overlaid HTML text stays legible.

pageContext — where the image is used

A short phrase in pictorial slot language, in English (it is machine guidance, not site copy). Examples: contained editorial photograph in a 3-column gallery, menu item thumbnail, full-frame editorial photograph with the left third kept as open, low-detail negative space.

• Describe copy-overlay placement as reserved empty space in photographic terms, never as text: write the left third kept as open, low-detail negative space — NOT hero with the headline overlaid on the left. Naming a headline or menu in the pageContext is the trigger for the model painting ghost text into that exact region — and so is design-comp vocabulary like hero cover background: prefer photographic slot language (editorial photograph, full-frame backdrop) over web-layout language (hero, banner, cover background).
• The structured aspectRatio field is authoritative for canvas shape; pageContext must not contradict it.

style

One of: photorealistic (default), digital-art, illustration, minimalist, flat-design, 3d-render, abstract, watercolor. Keep one style per site unless the design deliberately mixes.

aspectRatio — match the slot

• landscape (16:9) — the default for hero and banner images and wide feature/gallery rows
• ultrawide (21:9) — ONLY for full-bleed backgrounds spanning the viewport edge to edge; never for contained images, cards, or columns
• portrait (9:16) — dramatic tall images: full-height editorial shots, tall side-by-side panels
• card-landscape (4:3) — contained landscape slots: product cards, blog thumbnails, feature images in columns
• card-portrait (3:4) — the natural portrait-card shape: team headshots, tall product cards, framed insets; prefer over portrait for anything in a card or column
• square (1:1) — only when the layout slot is genuinely 1:1

A full-bleed cover BACKGROUND must be landscape or ultrawide — never square, portrait, or a card ratio. Grid/row consistency: all images displayed together in one row or grid MUST share the same aspect ratio — never mix.

siteContext and imageGrade (shared per call)

• siteContext: one sentence of subject matter ("A neighborhood bakery selling sourdough and pastries."). NEVER include the site or business name — a name in the prompt is what painted-in fake wordmarks stand in for.
• imageGrade: ONE site-wide photographic treatment (e.g. "warm natural window light, soft muted color, gentle film grain"), derived from the visual direction. Use the identical grade in every call for the site so all imagery reads as one photographic series.

No decorative or transparent images

Generated imagery is for CONTENT — covers, feature/gallery/card images, photographic bands. Never generate decorative assets: no ornaments, flourishes, crests, stamps, icons, or logo marks. They come out off-palette and geometrically wobbly, and small raster icons turn to mush. Decoration comes from theme primitives (separators, borders, spacing, type); feature icons: use none — let type and layout carry the hierarchy.

Cover blocks

For wp:cover backgrounds, set the same image URL on BOTH the block's url attribute and the inner <img> src. Wide cover images (landscape/ultrawide) are generated at 2K automatically.

Failure handling

• Safety-filtered image: rewrite that image's subject to avoid the flagged element and call generate_images again for just that image. One retry; if it fails again, treat as a permanent failure.
• Permanent failure: adapt the layout to work without that image (a color/gradient background, a text-led card). NEVER substitute an unrelated image, source an image from a web URL, or leave a reference to a file that does not exist.
