For the file flags.bmp according to specification the size for one flag has to be 16x12 pixel. famfamfam's flags are 16x11, so they would need to be rescaled/stretched which causes an ugly view on some of them. Also some flags are missing at famfamfam (f.e. ac, aq, ...) But at least after some hours of work: http://www.should.keepfree.de/flags.test.famfamfam.bmp
