Flags

Oh on that note. The css style:

img {
    width: 30px;
    height: 18px;
}

Should help prevent any strange image sizing bugs.

I'm pretty hopeless with css, if you could provide that as an entire code snippet with example <img> tag and everything I'd be happy to integrate. Is there any chance of it going wrong if I keep all the images 30x18 though?

So I just stick this in my styles.css file and everything sorts itself out?

Pretty much.

Unless you add more images which are not flags. That css snippet affects all images on the page.

Yeah, I said "all images" and "all <img> tags".
