What it does
This prompt instructs an AI image generator to transform a provided portrait into a full-bleed, photorealistic recreation of the classic “Home Alone” movie poster by preserving the subject’s real face and lifelike skin texture, matching the iconic shocked pose and red sweater, placing the two burglars behind the window in their original look and position, and outputting a print-ready 2:3, 4K cinematic poster with only the specified bottom title and tagline and absolutely no borders or margins.

Inputs
imageInputs
This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.
| Index | Required | Description | Allowed CLI flags |
|---|---|---|---|
| 1 | Yes | The portrait photo to transform into the “Home Alone” poster | --image-input-url <url> or --image-input-path <path> |
Models and options
This skill's modality is: image.
To discover which model values you can use (and which options keys/values are valid for each model), run:
betterprompt resources --models-only --json
Then filter the returned JSON array to entries where modality is "image".
How to run
Step 1: Collect inputs
First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:
betterprompt resources --models-only --json
Use only the models and option values that appear in the filtered results.
Then collect all inputs from the human:
- Required images:
- Exactly 1 images: image 1 (The portrait photo to transform into the “Home Alone” poster). Images must be provided in this order.
- Optional: model and options.
- Present the human with the default model
gemini-2.5-flash-image-previewand its available options. Look upgemini-2.5-flash-image-previewin thebetterprompt resourcesoutput (filtered to modality"image") and show itsavailableOptionsas:key: val1, val2 (default), val3 | key2: .... Mark a value(default)if it matches these defaults:{}. - If the human does not specify, defaults are used: model
gemini-2.5-flash-image-preview, options{}. Other models from the resources call are also available.
- Present the human with the default model
If the required images are missing, ask the human for what's missing. Do not assume or fabricate values. Tell the human: "Please provide images in this order: image 1 (The portrait photo to transform into the “Home Alone” poster)".
Step 2: Run via BetterPrompt CLI
Use the frontmatter's name as the positional argument (for this skill, use home-alone-movie-poster).
Command form:
betterprompt generate home-alone-movie-poster \
[--image-input-url <url>] \
[--image-input-path <path>] \
[--model <model>] \
[--options <options JSON>] \
[--json]
Notes:
- Pass each image using
--image-input-urlor--image-input-path, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.). - If the human does not mention a model, omit
--modeland BetterPrompt will use the default model:gemini-2.5-flash-image-preview. - If the human does not mention options, omit
--optionsand BetterPrompt will use the default options:{}. - If the run times out, the response will include a
runIdyou can use to fetch the result later.
Example (using defaults shown above):
betterprompt generate home-alone-movie-poster \
--image-input-url https://example.com/image1.png \
--model gemini-2.5-flash-image-preview \
--options '{}'
