# GPT Image 1.5 Image To Image
> Generate images from input images using the GPT Image 1.5 Image To Image model
## Overview
Generate images from input images using the GPT Image 1.5 Image To Image model. This model allows you to edit or modify existing images with text prompts. The process consists of two steps: create a generation task and query task status and results.
## File Upload Requirements
Before using this API, you need to upload your image files:
Use the File Upload API to upload your source image.
Learn how to upload images and get file URLs
After upload, you'll receive a file URL that you can use in the `input_urls` parameter.
* Supported formats: JPEG, PNG, WebP
* Maximum file size: 10MB
* Maximum 16 input URLs per request
* Images should be appropriate and follow usage guidelines
## Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Learn how to query task status and retrieve generation results
For production use, we recommend using the `callBackUrl` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

The URL to receive generation task completion updates.
Optional but recommended for production use.
- System will POST task status and results to this URL when
generation completes
- Callback includes generated content URLs and task
information
- Your callback endpoint should accept POST requests with
JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll
task status
- To ensure callback security, see [Webhook Verification
