(adsbygoogle = window.adsbygoogle || []).push({}); OK, so i keep on seeing flashing GIF images on peoples GB pages but whenever i try to upload one they never work. If its my avatar it will just be frozen on one single part of whats supposed to be a flashing image. If i try to stick one in the blog or something, nothing appears. Do they have to be a certain size or anything? Anyone know how to do it? cheers...
