What It Is
The media library is your website’s file cabinet. Every photo, logo, video, PDF menu or price sheet you upload to WordPress goes there, and you can reuse any file on multiple pages. Each item has details you can edit, such as its title, caption and alt text, which describes the image for people who cannot see it. You reach it from the Media menu in your dashboard.
Why It Matters for Your Business
For a small business, the media library affects both speed and search. Huge photos straight from a phone or camera can slow your pages, especially on mobile. Descriptive file names and alt text, like "bathroom-tile-remodel-oak-park.jpg" with a matching description, help search engines understand your images and can bring visitors from image searches. A tidy library also makes it faster to build new pages.
Good to Know
Resize and compress photos before uploading, or use a reputable image optimization plugin. Fill in alt text as you go rather than leaving it for later. Be cautious when deleting files, since an image may be used on a page you forgot about. And only upload photos you own or have permission to use.
