AI Hero Image and Background Generator

Make the image behind your headline, a wide banner or a wallpaper, framed for the screen it fills.

Rings of amber, honey and rose light from bullseye window glass gathered on the right of a warm plaster wall, the left two thirds plain and calm
One sheet of tangerine paper folded into a tent in the right third of a tangerine ground, its long hard shadow running left, the left half open
Looking down into a pool at noon: a net of white caustic lines on pale aqua tiles, a limestone edge on the right with one folded cream and cobalt striped towel
Folded amber tortoiseshell sunglasses with bottle green lenses in the right third of a coral pink plane, a crisp shadow with a warm amber glow in it, the left half empty

What is an AI hero image generator?

It makes artwork for website headers, banners and backgrounds. In Batch Banana, choose the aspect ratio and describe the scene, or start from a product photo. Leave a plain area for your headline and keep the subject centered for cropping. One image on Nano Banana 2.1 costs 10 credits.

Where the headline goes

Plan for desktop and mobile

A full-width hero is cropped to each screen, narrowest on phones. The dashed lines mark what a tablet and a phone keep of this 16:9 run, so the walker stands at the center of the dune and the headline goes in the open sky.

Edits

A hero from a phone photo, and its dark version

Both edits use the original image as a reference in Nano Banana 2.1. The kettle photo is also generated in Batch Banana. Drag the divider to compare.

Rings of amber, honey and rose light from bullseye window glass gathered on the right of a warm plaster wall, the left two thirds plain and calm

A wide website hero photograph for a glassware studio. Late-afternoon sun comes through a small leaded window of round amber, honey-yellow and rose bullseye glass panes, out of frame to the right, and throws soft overlapping spiraled rings of colored light across a warm off-white plaster wall at a slight angle. The rings gather in the right third of the frame; the left two thirds are plain warm plaster in soft even shade, calm and empty, where a headline will sit. No window visible, no objects, no furniture. Shot straight on with a medium-format camera, fine film grain, gentle falloff from light into warm shade. Palette: warm off-white, amber, honey, rose. No text.

One sheet of tangerine paper folded into a tent in the right third of a tangerine ground, its long hard shadow running left, the left half open

A wide website hero photograph for a paper goods shop. One large sheet of heavy tangerine paper, folded once into a crisp tent, stands on a seamless tangerine paper ground in the right third of the frame. Hard low sun from the right casts a long sharp shadow of the fold to the left across the ground, and the ground shifts from bright yellow-orange near the fold to deep burnt orange at the top edge. The left half of the frame is open, calm tangerine paper, where a headline will sit. Nothing else in the frame. Studio photograph with a medium-format camera, visible paper fibers, crisp edges. Palette: tangerine, burnt orange, one deep shadow. No text.

Looking down into a pool at noon: a net of white caustic lines on pale aqua tiles, a limestone edge on the right with one folded cream and cobalt striped towel

A wide website hero photograph for a swim school. Looking straight down into a clear outdoor swimming pool at noon: sunlight draws an even net of bright white caustic lines with small sun glints over pale aqua tiles beneath the water. A smooth white limestone pool edge runs along the right side of the frame, with one folded cream and cobalt striped towel on it. The left two thirds are open water with calm, even caustics, where a headline will sit. No people, no lane ropes, no ladders. Medium-format film, natural color, gentle grain. Palette: aqua, white limestone, one stripe of cobalt. No text.

Folded amber tortoiseshell sunglasses with bottle green lenses in the right third of a coral pink plane, a crisp shadow with a warm amber glow in it, the left half empty

A wide website hero photograph for an eyewear brand. One pair of sunglasses with a thick acetate frame in translucent amber tortoiseshell and bottle-green lenses lies folded on a vast seamless coral-pink plane, in the right third of the frame. Hard midday sun from the top right casts one crisp shadow beneath, and light through the amber acetate throws a small warm glow onto the ground. The left half is empty coral-pink ground, where a headline will sit. No other objects. Studio photograph with a medium-format camera, sharp focus on the hinges, real materials. Palette: coral pink, amber tortoiseshell, bottle green. No text, no logo.

A small walker in a cream shirt on the crest of an apricot dune in early morning, the ridge curving across the lower third, open pale sky above

A wide website hero photograph for an outdoor travel company. A smooth apricot sand dune in early morning, seen from a low distance: one clean ridge line curves across the lower third of the frame, sunlit burnt orange on one side and in soft ochre shade on the other. A single small walker in a cream linen shirt stands on the crest at the horizontal center, about one twentieth of the frame height, with a long thin shadow. Above the ridge, a clear pale peach-to-blue morning sky fills the top half, empty and calm, where a headline will sit. Medium-format film, warm grade, fine grain; scale does the work. Palette: apricot, ochre, pale sky blue. No text.

The same kettle alone on a pale oak shelf against warm white plaster in the right third, morning sun casting its shadow on the wall, the left half calm and empty

Image 1 is a phone photo of a stovetop kettle. Make a website hero for the kettle's maker: the same kettle with the same sage-green enamel body, pale ash wood handle and brass spout and whistle, standing alone on a plain pale oak shelf against a warm white plaster wall, in the right third of the frame. Early morning sun from the left casts the kettle's soft shadow and one slanted band of light across the wall. The left half is calm, empty plaster where a headline will sit. Nothing else on the shelf. Medium-format photograph, natural color, fine grain. No text, no logo.

The same dune at blue hour for dark mode: a deep indigo sky with a thin crescent moon on the left, the walker and the ridge unchanged

Image 1 is a website hero. Make the dark mode version of the same image: the same dune, the same ridge line, the same walker in the same place and size, the same framing. Change the time to blue hour after sunset: the sky a deep, even indigo with a thin crescent moon high on the left, the sand in cool violet-blue shade with a faint warm glow left on the ridge. The top half stays empty for a light headline. No text.

A very wide 21:9 banner of a terracotta stucco wall in late sun, a date palm shadow at each end, the long center plain, a strip of sand below

A very wide website banner photograph. A long sunlit terracotta stucco wall seen straight on in late-afternoon sun, filling the frame. The soft-edged shadow of a tall date palm falls across the wall at the far left, and a second palm's shadow at the far right; the long center of the wall is plain, warm, evenly lit terracotta, empty for a title. A strip of pale sandy ground along the bottom edge. Nothing else: no people, no animals, no benches, no doors. Film photograph, warm grade, fine grain. Palette: terracotta, sand, soft brown shadow. No text.

The dune recomposed as a tall phone wallpaper: the walker small on the crest in the lower third, open pale blue sky above

Image 1 is a wide website hero. Recompose it as a tall phone wallpaper: the same dune, light, colors and the same small walker on the crest, now in the lower third and centered, with the open morning sky filling the upper two thirds for the clock and the notifications. Same film grain and warm grade. No text.

One background photo on four models

The same prompt, run once on each model, with the credits each image cost.

Same prompt, every model

A square background photograph for a website: morning sun through a tall clear glass of water standing on a pale sage linen tablecloth. The glass sits in the lower right and throws a long bright caustic shadow, a ribbon of light inside a soft shadow, toward the lower left. The upper half of the frame is plain linen in gentle light, calm and empty for a headline. Seen from slightly above. Medium-format film photograph, natural color, fine grain. No other objects, no text.

How it works

How to make a hero image

  1. Pick the frame first

    16:9 for a page hero, 21:9 for a wide banner, 9:16 for a phone wallpaper. The frame is a setting, so the prompt never has to name it.

  2. Leave room for the words

    Describe a calm area where the headline goes, and keep the subject near the center. Phones crop a full-width hero the most.

  3. Refine your chosen image

    Run the scene on a few models and keep the one that fits the page. Upscale it before it goes on a large screen.
