Question 1

What size should a share image be?

Accepted Answer

1200×630 pixels (1.91:1) works nearly everywhere. Keep important text near the center — some platforms crop to a square and cut off the edges.

Question 2

I changed the image but the old one still shows?

Accepted Answer

Platforms cache share metadata. You need to re-scrape the URL in Facebook's and LinkedIn's own debugging tools; WhatsApp's cache simply has to expire on its own.
