Flickr works fine on this board!
That's where all my images come from, from the avatar to the logo to all the pics I post. If anyone is having problems it is most likely because you set your account to 'private' which means others can;t see your images. I strongly recommend people using Flickr as it is much easier to manage pics there than on Photobucket, mainly as sizing is done automatically -- and if you pick the small size image it is exactly the maximum dimensions for avatars here (eg the size of my avatar).
