Atlas Nanobanana Image-to-Image 🖼️

Edits and combines images using the AtlasCloud Nanobanana 2 Edit model (google/nano-banana-2/edit).

Token Setup

Before generating images, you need the user's AtlasCloud API token.

Check memory for atlascloud_token.
If not found, ask the user: "Please provide your AtlasCloud API token to get started."
Save the token to memory as atlascloud_token so it is not needed again.

How to Generate an Image

Step 1: Write the params to {baseDir}/params.json.

Step 2: Run the script:

bash

node {baseDir}/generate.js <TOKEN> {baseDir}/params.json

Step 3 — REQUIRED: After the script finishes, run this bash command to read the generated URL:

bash

cat {baseDir}/last_url.txt

⚠️ CRITICAL: Step 3 is mandatory and irreplaceable. The correct URL is ONLY in last_url.txt. Run cat as a separate bash command and use the exact text returned. Never use a URL from the conversation history, previous files in the context, or any other source.

Report the URL from last_url.txt to the user.

params.json — Payload Correto

⚠️ IMPORTANT: Never include media_resolution in the payload — it causes an HTTP 500 error.

json

{
  "prompt": "Replace the dress on the model in image 0 with the dress from image 1. Preserve identity, face, pose, and lighting.",
  "images": [
    "https://url-of-base-image.png",
    "https://url-of-reference-image.png"
  ],
  "aspect_ratio": "16:9",

}

Available Fields

|---|---|---|---| | prompt | ✅ yes | — | any text | | images | ✅ yes | — | array of 1–4 URLs | | aspect_ratio | no | 16:9 | 1:1 | 4:3 | 3:4 | 16:9 | 9:16 | 21:9 | | resolution | no | 1k | 1k | 2k | 4k | | output_format | no | png | png | jpeg | | enable_web_search | no | false | true | false | | enable_image_search | no | false | true | false | | enable_base64_output | no | false | true | false | | enable_sync_mode | no | false | true | false | Do not include media_resolution — it causes a 500 error.

Prompt Tips for Image-to-Image

Refer to images by position: "image 0" (base), "image 1" (reference).
State clearly what to preserve: face, pose, proportions, lighting, background.
State clearly what to replace: the clothing, the background, the style.
Use negative instructions: "DO NOT change the face", "DO NOT transfer human elements from image 1".

Error Handling

Error	Probable Cause	Solution

| HTTP 500 | media_resolution present in payload | Remove media_resolution from params.json | | HTTP 500 | Invalid or expired token | Request a new token from the user and refresh memory | | Link does not update | Step 3 was not executed | Run cat {baseDir}/last_url.txt as a bash command | | Timeout | Resolution too high | Try again with "resolution": "1k" | | Job failed | Image URLs inaccessible | Check if images are public |

When to use this skill:

"swap the clothes in this photo"
"apply the style from image 1 to image 0"
"edit this image using another as a reference"
"change clothes in the photo"
"combine two images with AI"
