What is the difference in path between ./image and just image?

Question

HTML

Example:

<img src="./image.jpg"  alt="картинка"> 
<img src="image.jpg"  alt="картинка">

In my opinion, it's one and the same.
Why 2 spellings, what's the difference?

Answer 1

. - path from the current file
/ path from the root file
In your case, they are the same, so there is no difference.

Answer 2

! impractical to keep HTML and images in the same directory
! relative paths are written through .. and allow you to refer to an element from another directory
