Guidelines for Signature (pictures)

[Hermosa11]

I don't get it. I had about 5 photos of noted size below. I get a PM saying I must have 3 photos only. Fine...I make the change. But yet I see some signatures with soooo much space for tickers, or how many hotels they've stayed at, etc. What gives? I use up less space than their 6 tickers?

Please explain. Thank you in advance.
