Apologies for the delay!
They actually are there but they are beign rendered incorrectly due to a styling conflict.
See this style:
The "max-width:100%;" is causing a conflict. Although my plugin attempts to over-ride that conflict, somehow it's not working.
If you can remove the "max-width" from that element in your style sheet, it will work.
It doesnt look like removing it will negatively affect anything else on your site either.
