can i hook the output?

Bj?rn,

I just bought you three coffees, your plugin is brilliant, thank you! bought you some coffee!

I’d like to add some more sources to the output though, are there any hooks at all? If not I was going to use simple_html_dom_parser, but before going down that road I just wondered if there might be a more efficient way to manipulate the webp output.

Thanks again for the plugin

Andy
