What happens when you save an image?

Question

Adobe Photoshop

For example, I sent an image (exactly as an image, not a file) to VKontakte, then saved it, then sent it again and saved it again. What will happen to the original image?

Answer 1

Some have been doing this for 8 years. Clear enough.

In June 2012, this public was launched by blogger and network artist Alexander Dobrokotov. In short, nothing happens in it. Dobrokotov simply manually uploads the same photo of the President of Russia every day, saves it to his computer and uploads it again the next day. Every day, a picture taken from the official website of the Kremlin loses a little in quality due to image compression algorithms.
