Where do you place your pictures for your website?

Hello everybody!

Where do you place your pictures for your website? For example, if you are taking pictures in your post (possibly many pictures), are you placing them in your host or elsewhere, such as imgur, demandstudios, etc.?

Where is the best place to upload it? (fastest to load, etc.)

or what do you call these types of websites? Where can I see the list of the best?
