Steps to reproduce the issue

Go to frontend, with breadcrumbs enabled, do an audit test with chrome. Then you see that the divider is missing a width and height tag.

Expected result

No issue

Actual result

Specify image dimensions (1)
A width and height should be specified for all images in order to speed up page display. The following image(s) are missing a width and/or height:
arrow.png
(2 uses)

System information (as much as possible)

Additional comments

We need to parse the height and width on the JHtml:_('image') side.

for example this code we use to show the width and height:

$location = JUri::root() . $attachment->getUrl();
$data = getimagesize($location);
$width = $data[0];
$height = $data[1];


<img src="<?php echo $attachment->getUrl(); ?>" width="<?php echo $width ;?>" height="<?php echo $height ;?>" alt="" />

This is needed for a w3c validation checks, or any other html checks like in the inspector from chrome (audit - ).

Now if you check a clean protostar template. he is showing a dimension notice to fix the height and width tag.
