Can someone fix this regression in the HTML exporter - 294dcb.

The problem is with hyperlink whose description is an image. So have
unicorn logo on the dir where you save this file.

Would appreciate if the whole document exports fine without any
regression.

Will releasing a 7.5.1 version be a good idea considering that HTML
exporter had quite a bumpy ride in the last few weeks.
