A << browse("<body font=Tahoma background=effect.png>[text]</body>","window=deckEditor.cardinfo")
Problem description:
Doesn't seem to be printing a background image. the image is in the project folder and i've done it in a normal html files and it works fine.
This will take the effect.png file from your game's resources and load it into the client's browser cache so it can be accessed as a local file. I recommend looking browse_rsc() up in the reference for more info.
