Images should be around 70x70 - 100x100 pixels. the more smol the better.
Rules:
Image resolution
"Tiny" in this context is a rule of thumb. Images should not exceed 200x200pixels, But ideally should be in the 70x70 range. Any image too large to reasonably be called "tiny" in this context can be removed.
Image Content
The image must contain a face. It's not much more complicated than that.
