Error [108]: "there is no attribute X"

This is that line:

<a href="http://img.alibaba.com/photo/101357875/Lost_Season_1_4_Boxset.jpg"
rel="gallery.posts"><img
src="http://img.alibaba.com/photo/101357875/Lost_Season_1_4_Boxset.jpg"
border="0" alt="Click the image to open in full size."
class="tcattdimgresizer" onload="NcodeImageResizer.createOn(this);"
/></a><br />
