Why the wrong image appears

Snapchat reads og:image first, then falls back to twitter:image. Common causes:

1. og:image points to the wrong URL
2. og:image is missing, so Snapchat uses twitter:image which points elsewhere
3. Cached from a previous crawl (cache lasts ~30 minutes)
4. Correct image, but Snapchat’s center-crop cuts off important content
5. Multiple og:image tags on the page – Snapchat picks one you didn’t intend

Diagnosis steps

1. View page source – check both og:image and twitter:image values
2. Load the image URL directly in a browser
3. Search your HTML for duplicate og:image and twitter:image tags
4. Wait 30 minutes – the short cache means fixes propagate quickly

The fix

Correct your og:image tag, wait 30 minutes, re-share. Snapchat’s short cache makes image fixes easier than on most platforms.

curl https://yoursite.com/page | grep -i "og:image\|twitter:image"

Verify one og:image tag pointing to the correct absolute HTTPS URL.
