How do I install the SlashImage plugin?

1 min read · Last updated June 2026

Install the SlashImage plugin the way you install any WordPress plugin - search for it in your admin, or upload the plugin zip - then activate it.

From your WordPress admin

  1. In WordPress, go to Plugins > Add New.
  2. Search for Slash Image.
  3. Click Install Now, then Activate.

From a zip file

Use this if the plugin isn't in the directory search yet, or if you simply prefer it - uploading the zip always works.

  1. Download the SlashImage plugin zip.
  2. In WordPress, go to Plugins > Add New > Upload Plugin.
  3. Choose the zip, click Install Now, then Activate.

After activating

Once the plugin is active, it prompts you to add your API key so it can start optimizing. See How do I connect my API key to WordPress?.
