Map tip display text in QGIS 2.16: pictures not showing up anymore!

This one worked for me:

<div style="width:400;height:320">
<div style="height:20; margin: 0 auto;">
[% "filename" %]
</div>
<div style="height:300; margin: 0 auto;">
<img style="max-width:400px; max-height:300px;" src="[% "filepath" %]" />
</div>
</div>
