Installation
Install Vacuum Image Optimizer from WordPress.org, GitHub, or a local ZIP package.

Install from WordPress.org
- In WordPress admin, go to Plugins -> Add New.
- Search for "Vacuum Image Optimizer".
- Click Install Now.

- Open Media -> Vacuum Image Optimizer.
After activation, the plugin creates its required options, queue table, backup directory, and first-run setup state.
Install from a ZIP
Use this path for a GitHub release asset or a local QA package.
- Download the installable ZIP.
- In WordPress admin, go to Plugins -> Add New -> Upload Plugin.

The runtime plugin includes a lightweight PSR-4 fallback autoloader. Composer is not required for normal WordPress installs.
After activation
