Ranking system not achievable with 'Badges'

Hello,

I need help with implementing a ranking system because the 'Badges' facility does not help me to do so.

(a) Imagine that my website is based on the British Army ranks and I want my members to progress from Cadets to Field Marshal as their total points increases. Cadet (0-49 points), Lieutenant (50 - 99 points), Captain (100 - 149), Major (150-199), Colonel (200-299), Brigadier (300-399), General (400-699), Field Marshal (700+).

(b) Each member can only be at one of the ranks and will have a display in his profile to show his rank such as :- Cadet.png (0-49 points), Lieutenant.png (50 - 99), Captain.png (100 - 149), Major.png (150-199), Colonel.png (200-299), Brigadier.png (300-399), General.png (400-699), FieldMarshal.png (700+).

(c) Looking at my jpeg, I want the png picture to be displayed in location red OR green BUT if possible in location blue ALSO.

How can I achieve the above, even if I have to hack a 'case' statement or 'if' statement into php files? I know that it will not be supported but this ranking requirement is vital to my website concept.

Thanks in advance.
