## What it is
Picasso is a powerful image downloading and caching library for Android that simplifies loading images into ImageViews, often in one line of code. It handles adapter recycling, image transformations, placeholders, and automatic memory and disk caching.

## Use cases
- load images from a url into an imageview in android
- cache downloaded images in memory and on disk
- resize and crop images to fit layouts
- show placeholder images while downloading
- cancel image downloads when adapter views are recycled

## When to choose
- maintaining a legacy Android app already using Picasso
- you need a battle-tested image loader for View-based Android UIs

## When to avoid
- starting a new Android project (the library is deprecated)
- using Jetpack Compose UI
- you want an actively maintained alternative like Coil
