How about adding an ALT tag to the flag images for those of us who have this facility enabled? The images are quite small and it's difficult or impossible to determine which countries some of the flags represent. For example: the flags of Luxembourg and the Netherlands are almost identical, just a slightly different shade of blue on one of the bars. Paraguay and Croatia have very similar flags, as does the Slovak Republic and Slovenia. I'm sure there must be lots of other examples too.
An ALT tag would remove the ambiguity as you could identify a player's country by simply hovering your mouse pointer over the flag.
Just an idea!
