@Kris Wood i don't think this is possible - i've tried every possible html/css combination and it doesn't help. I think Freemarker or BFO must strip some of that out. We've resorted to setting a default percentage size of image and using a custom field to allow users to change it if the default makes it too small or large. 😕 But if you figure it out please let me know, I'd love to hear it!
