In the old infobox, I can add an .ogg file to the video-image line, and it turns out just fine. But I seems unable to do so with the portable infobox. Anyone here has the code to do so?
I don't think OGG files can be inserted as images. You can create a <data> tag for inserting an OGG file and then use it like |audio = [[File:Something.ogg]]. If you don't want to pass multiple OGG files into that parameter you could do
