* Weapons can now download the “raw”image size, which is the weapon art without a background * Characters now download the “detail” image size, which is a horizontal crop of the character’s art * Summons now download the “detail” image size, which is a horizontal crop of the summon’s art * Summons also download “ls” and “m” instead of “party_main” and “party_sub”, as they match the aspect ratio of weapon sizes better, which should make our lives a lot easier.
