Avatarity doesn't allow remote hotlinking of our avatar images. This is when other sites load our images directly. We have to do this because otherwise the bill for our traffic would be too high for us to keep going. However, many forums do not allow you to upload an avatar to their site - so hotlinking is the only option with them. For places like that we have made a Free Image Hosting Services page, which lists some free services you can use to hotlink to your images. Happy hosting!
