Unsplash is also a good source of free stock photos.

Pexels is giving free photos, without watermark, to use even without giving credit (I do give credit anyway).

I have never used pixabay before. This is because I have hadn't any business with photos or videos that they provide for now.

Pixabay will be a thing of the past. Their pictures are boring compare to ai.

I use the unsplash. I find it a good service. I think they have some of the quality HD photos and it is a good in general to be honest.

I think most of their quality photos here, you need to have a subscription to download them

AI images are definitely shaking things up and can be super creative and unique.

Pixabay is a licensed free photos providing platform, the photos are used without anyone's permission so that the bloggers etc does not have the problem of copyright infringement. But Pixabay is not the only one, apart from this there are many other websites from which free photos can be taken for personal or commercial use.

Some of the alternatives are-
Freeimages.com
FreeDigitalPhotos.net
Freepik
Photogen
PikWizard
Pexels
PostImage.org
StockSnap
Unsplash
Openverse
Gratisography
Burst
Reshot
500px

These are just few, there are so many.
Which one is your favorite?

I have been using Pixabay for my online image needs for a number of years. I don't think it is easy for me to think of an alternative. But will keep this bookmarked just in case.
