to have all Admins have the same Rank Image, and all Moderators to have the same Rank Image:
change this:
case "2"
if fM_POSTS < CInt(intRankLevel1) then Star_Level = ""
if (fM_POSTS >= CInt(intRankLevel1)) and (fM_POSTS < CInt(intRankLevel2)) ...
if (fM_POSTS >= CInt(intRankLevel2)) and (fM_POSTS < CInt(intRankLevel3)) ...
if (fM_POSTS >= CInt(intRankLevel3)) and (fM_POSTS < CInt(intRankLevel4)) ...
if (fM_POSTS >= CInt(intRankLevel4)) and (fM_POSTS < CInt(intRankLevel5)) ...
if (fM_POSTS >= CInt(intRankLevel5)) then Star_Level = "<img src=icon_star_" ...
case "3"
if (fM_POSTS < CInt(intRankLevel1)) then Star_Level = ""
if (fM_POSTS >= CInt(intRankLevel1)) and (fM_POSTS < CInt(intRankLevel2)) ...
if (fM_POSTS >= CInt(intRankLevel2)) and (fM_POSTS < CInt(intRankLevel3)) ...
if (fM_POSTS >= CInt(intRankLevel3)) and (fM_POSTS < CInt(intRankLevel4)) ...
if (fM_POSTS >= CInt(intRankLevel4)) and (fM_POSTS < CInt(intRankLevel5)) ...
if (fM_POSTS >= CInt(intRankLevel5)) then Star_Level = "<img src=icon_star_" ...
to this:
case "2"
Star_Level = "<img src=""gamecube_ranks_0.gif"" width=""100"" height=""22"" border=""0"">"
case "3"
Star_Level = "<img src=""gamecube_ranks_0.gif"" width=""100"" height=""22"" border=""0"">"
Then just change the Rank Image file name and the width and height of each of them in the code you added.
case "2" is for Moderators
case "3" is for Admins
