The Flexible One
To be honest, I feel like that may be pushing things a bit into the “Rule #3” territory, since it’s an existing image with just eight other, unrelated images bordering it. If there was a significant artistic value to the bordering images so that they enhanced the existing pony image, it may be fine, but there’d have to be a a clear distinction that it’s not just eight random pictures plus a pony.
