## What it is
Invoke-PSImage is a PowerShell tool that encodes a PowerShell script into the pixels of a PNG image using steganography, then generates a oneliner to execute the payload. It can embed payloads in the least significant bits of an existing image or create new images, supporting execution from disk or the web.

## Use cases
- hide a powershell script inside a png image
- generate a oneliner to execute a script embedded in an image
- embed mimikatz payload in a picture for red team ops
- encode powershell payload into image pixels for stealth delivery
- host an image on the web and execute the embedded script remotely

## When to choose
- you need to smuggle a PowerShell script past simple inspection by hiding it in an image
- you want a self-contained oneliner that decodes and runs a payload from a PNG
- you are doing red team or penetration testing on Windows environments

## When to avoid
- you need a defensive or detection tool rather than an offensive payload encoder
- your target is not Windows PowerShell
- you need robust, modern tooling - the project has not been updated since 2019
