What size should the og:image be?

1200×630 pixels, a 1.91:1 ratio, under 8MB and ideally under 300KB. Anything much smaller than 600×315 gets rendered as a small square thumbnail instead of a large card, which is a considerable difference in click-through.

Why is my image not showing when I share the link?

Usually a cache. Facebook and LinkedIn both cache the first scrape of a URL for a long time — use their own debugger tools to force a re-scrape. The other common cause is a relative image URL; og:image must be absolute, including the scheme.

Do I need Twitter tags as well?

X falls back to Open Graph tags when no Twitter card tags are present, so the basics are covered. Adding the Twitter tags gives you control over the card type — a large summary image versus a small one — which is worth the four extra lines.
