Take the size of an image

Question

There is the possibility to take the size via javascript of an external image to my directory?

For example in this use:

.divExterna{
background-image:url(http://www.backsite.com.br/datafiles/suite/escritorio/aplicativo/conteudo/album_fotografico/769.jpg),
height: seu_tamanho
}

I would like to take your size to apply as my div’s height.

Answer 1

So (as it has structured css) will not give because the image is in the background, can however do so:

div {
 display: inline-block;
 border: 2px solid yellow; /* isto é só para ver a div (altura/comprimento) */
 height: 150px;
}
img {
   height: 100%; 
}

<div>
  <img src="https://catracalivre.com.br/wp-content/uploads/2015/10/imagens-3D_11.gif">
</div>

This way the image will always have the height (height) that defined in the parent element (div in this case)
