If I put this code in the editor
Code:
<div align="center">
<img src="../images/000004.jpg" style="width: 30%"/>
<p class="center">Picture 1</p>
</div>
and try to change the width of the image ("width: 50%", "width: 70%" and so on) the rendering of the changes is correct.
BUT if I try to change the HEIGHT of the image (style="height: 30%", style="height: 50%", style="height: 70%", and so on) changes are not rendered at all.
