How dvlr.it finds and displays suggested media

Wondering why your link preview shows the wrong image — or no image at all? Learn how ACME selects images and metadata from your links, and how to make sure yours always looks great.

When you paste a link into dlvr.it, we automatically scan the page and suggest images and text to go along with your post. It's designed to save you time — but if something looks off, this guide will help you understand what's happening and how to fix it.

How dlvr.it picks images from your link

dlvr.it scans the page as soon as you paste a URL and looks for the best available images. Here's what happens behind the scenes:

  • We check for Open Graph tags (like og:image) in the page's HTML first

  • Only the first 15 images that pass our quality check are considered

  • To qualify, an image must include a width or height attribute and be at least 200×200px

Tip: Make sure your images are tagged correctly in HTML. A well-formatted image looks like this: <img src="link-to-your-image" width="600"/>

How dlvr.itchooses which image comes first

Not all images are treated equally. dlvr.it works through this priority order:

  1. Open Graph & Twitter Card tags — og:image, og:image:secure_url, and twitter:image are checked first. These tags exist specifically to control how your content appears when shared.

  2. Images inside article content — If no OG tags exist, we look inside <article> tags or elements marked as the main body of the page.

  3. Everything else — If neither of the above is available, we scan the rest of the page for usable images.

We recommend following the Open Graph Protocol when setting up your site — it gives you direct control over how your content appears across ACME and other platforms.

How to check what your link actually shows

Not sure what's being pulled from your page? Run your URL through the Facebook Sharing Debugger. It's free, takes seconds, and shows you:

  • Which metadata is available on your page

  • Which image is being selected

  • How to force a refresh if you've recently made changes

Note: These tips apply to pages you own and control. If you're sharing a link to someone else's site, the images shown are determined by how that site is set up — there's no way to change them from your end.

Common issues and how to fix them

    ​

    ​

  • Use images that are at least 200×200px with width or height declared in the HTML
    ​
