avatars cant use CAPITAL fileext like JPG

[Ghost_ufa]

bp-core-avatars.php, function bp_core_check_avatar_type should use case-independent regexp patterns:

if ( ( !empty( $filefiletype ) && !preg_match(’/(jpe?g|gif|png)$/i’, $filefiletype ) )

!preg_match( ’/(jpe?g|gif|png)$/i’, $filefilename ) )
