Why do the images for the special sets (purple titles) not show up? Or the prices?
All images are taken from Gatherer so if there is no image, it isn't there. As for prices, this means nobody is selling them as all prices are taken from TCGPlayer.
Next version will have fix for the images, iMtG will show image from another expansion with 'Substituted Image' label. At some point I will also get the iMtG image server back online.
