What is the difference between src=“/images/logo.gif” and src=“images/logo.gif”?

Question

is equivalent to

But

Answer 1

images/logo.gif

It's relative and means: Go to a folder called images and then get the resource logo.gif

./images/logo.gif

It's relative and means: From the current folder (the dot means this) go to a folder called images and then get the resource logo.gif

As you can see the first two mean the same, finally the last one

/images/logo.gif

It's absolute and means: From the root of the web server or the file system or whatever (the slash means this) go to a folder called images and then get the resource logo.gif
