Does a webpage load images slower if there are multiple sources?

Scenario 1: I post pictures on my Facebook profile and create a webpage that has image SRCs linking to the Facebook profile

Scenario 2: I link my SRCs to images from Google searches. This means multiple sources for my images.

Is scenario 1 faster than scenario 2 since it’s pulling from one page, or are they the same because each image SRC is a request that takes time to process depending on the source?
