    Since you linked jQuery to your document, then you can use it to add a class onload. transition CSS will do its job from here.

    I suggest to use background-size instead transform:

    $(document).ready(function() {
  $(".sliderimg").addClass("loaded");
});
    div.sliderimg {
  height: 300px;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  transition: 5000ms linear 1s;
  background-size: 100% auto;
  position: relative;
}

div.loaded {
  background-size: 105% auto;
}

    I’m not sure if transitions occur on document load. I would use an animation instead:

    @keyframes example {
  from {transform: scale(1, 1)}
  to {transform: scale(1.05, 1.05)}
}

div.sliderimg {
  animation-name:example;
  animation-duration:5s;
  animation-fill-mode: forwards;
}
