Certain skins no longer working

[georgecaths]

Hi all, I've tried downloading these 2 skins:
https://forum.plutonium.pw/topic/33367/zm-6-origins-staffs-camo-and-6-origins-pap-camo?_=1720666497161
https://forum.plutonium.pw/topic/33339/zm-3-blundergat-camo-for-motd?_=1720666761493
Neither seems to work in my images folder, which seems universal as someone else had the same issue. Any idea why? Thanks.
