Addition to the query string as that's pretty much the cause of all these problems, I rather suggest to put the autostart/height/width/transparency and the actual URL in data-attributes rather than the query string to not only avoid caching problems with CDN and Cache Plugins but also of course avoid these kind of problems with security plugins like BPS.
That would be really nice to actually have, in case you feel like it I could always take a crack at the code if you allow me to modify/contribute to it via Github or alike?
Let me know what you think!
