D) Previewing Flames:
.....I) Previews should be images, videos or gifs only.
.....II) Flame sales must have at least one preview with the entire flame against the default white background and without any flame texture unless requested otherwise by the buyer.
.....III) Flame IDs must be posted any time a flame is being sold (e.g. the first post of selling threads and any other posts in buying threads). See this post for how to check the flame ID.
