Hi,

suppose you have

h1 {
  background-image: url("/images/logo.png");
}

h2 {
  background-image: url("/images/logo.png");
}

result is

h1 {
  background-image: url("/images/logo.png?v=MkVD9BBdWw2WA3dGctPEc3M4OGM?v=MkVD9BBdWw2WA3dGctPEc3M4OGM");
}

h2 {
  background-image: url("/images/logo.png?v=MkVD9BBdWw2WA3dGctPEc3M4OGM?v=MkVD9BBdWw2WA3dGctPEc3M4OGM");
}
