Baby spit up vs vomit

Janet • First time mommy to Christopher born September 6.
My son spits up alot, but he is a happy spit-upper. He eats all his breastmilk (he is ebf) and has a few minor spit-ups, he doesn't cry and isn't fussy. Occasionally, he will have the below spit-up. Is this spit-up or is this vomit?
