I can understand wanting higher quality looking flags but the ones you're using look ugly.
What? Get your dick out of that rat and be specific
These are the flags that are used currently, they look fine when there very large but when there reduced they look ugly.http://www.famfamfam.com/lab/icons/flags/
These are the flags that vichan, 4chan and many other imageboards use since they look good and are free to use.
