Allegorical Engraving Cover
Turn an article’s central argument into a finished black-and-white engraved cover built around one clear visual allegory. It gives editors and writers a distinctive, cohesive lead image for essays, newsletters, and series that need an idea understood at a glance.
You bring
- Complete article text or a sufficiently detailed draft
You get
- Three approval checkpoints that keep the article reading, metaphor, and final render brief under your control
- One original visual argument built from a concrete object, a surreal transformation, and only a few supporting signs
- One text-free 16:9 black-and-white cover built as a continuous full-frame scene rather than an illustration beside a blank panel

Choose a text-free or titled cover
Decide first whether the title sits on the image. Text-free covers leave the headline to your page and survive every crop; titled covers work on their own when shared, but need a Skill that places exact text.

Blog cover image FAQ
What these Skills do not do
- They do not make email newsletter headers or YouTube thumbnails.
- The engraving Skill does not render headlines; use a titled cover for that.
- They are not stock photo services.
What size should a blog cover image be?
A 16:9 image (for example 1600 × 900) works for most blog themes and shares well. Keep the subject near the centre so it survives a square thumbnail crop.
What is the difference between a cover image and a featured image?
Usually none: the featured image is the one your blog uses for the post, shown as the cover at the top and as a thumbnail in lists and shares.
Can the cover include my article title?
Allegorical Engraving Cover is always text-free. For a cover with an exact title and logo, use OpenAI Style Poster.
How does the Skill pick a metaphor?
It reads the article, states the argument it found, proposes one concrete object with one surreal change, and waits for your approval before rendering.
