That's actually a good idea... Thanks for pointing it out! (I actually had to Google what "hotlinking" meant, because I'm not very smart with this stuff...)
I actually prefer if people hotlink to my stuff, that way any updates I do to badges etc are applied across every site, so it has its uses.
and I am sorry about the non-transparency. You can fix that when your using it on your website. ;o;
I think CSS is the fun bit of webdesign, enjoy it!
