Images
Preview ImagesMost of the time you won't want to download the original large image, just get a small preview. This is possible simple by adding "/small" onto the end URL. This will give you a small 200px version. This will work with TheAudioDB.com and Fanart.tv URL's in exactly the same way hopefully :)
