My JCK editor insert images with size paramaters like this :
<img alt="" src="http://XXX.jpg" style="width: 900px; height: 560px;" />
Then smartresizer plugin apply croping but generates a missing quote in the style tag like this :
<a href="http://XXX.jpg" style="background:none;" onclick="return hs.expand(this)" ><img alt="" src="http://XXX_thumb_medium900_520.jpg" style=" /></a>
If I remove manually (in the source editor) the size tag
style="width: 900px; height: 560px;"
everything is ok
