player.swordimg with custom swords

[AlexanderK]

I just switched my custom swords from player.attr[3] to player.swordimg and it doesn't work at all.

Setting the swordimg (player.swordimg=...) serverside will do nothing and setting it clientside will only change it for the player, all the others still see sword1.png.

Do the swords have to have special names? Right now they're named like "sorna_sword_sword1.png". Is there any other way to do this?
