Ryan at CyberNet talks about the Firefox logo which is possibly the world’s largest. The logo stretches 20502 x 19839 pixels in size (approximately equal to 400 Megapixles) and weighs 9.66MB. You can’t upload this photo to Flickr, Imageshack because they impose a image size limit.
Ryan tried to open the logo in Windows Picture Viewer, but it crashed Vista, so he took a different approach and tried to render it in Firefox Browser. It took 4 minutes to fully render. Guess what?, Firefox wasn’t able to scale it proportionally.
The Firefox Crop Circle constructed in an oat field near Amity, Oregon would still retain its title as the World’s Largest Firefox logo, but this logo can be named as the World’s Largest logo to fit inside your computer.
Anyway, You can get the Firefox logo in Adobe Illustrator or EPS format so that you can scales it to any size and compete with this logo, you can download it here
