User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20131205075310

Steps to reproduce:

view the web site http://tvjl.org.uk, reset scale to 100% (ctrl-zero) and scale down once (ctrl-minus)


Actual results:

The "Maidenhead Marlins" image (in the middle, ie 6 from the left or right) is distorted.
if you right click it and view image, it is ok.

The relevant HTML is

<a target="_blank" href="http://www.maidenheadmarlins.com/">
<img border="0" src="images/Clubs/Maidenhead.gif" title="Maidenhead Marlins" width="100" height="70"></a></td>
<td>



Expected results:

scaled in a way that didnt look very distorted.  If you scale up/down with ctrl-plus or ctrl-minus it looks ok

Setting image.high_quality_downscaling.enabled = false helps
