Thanks for your reply ,Cavan1:)
I made .zip with .bootskin and permission file and I uploaded.Everything worked fine.Permission file is .PNG;a full and detailed screenshot of email sended by the walls author in order to allowing me to post my works.Is there something wrong with this?I also wrote in Description who the walls author is,and posted link;I wrote as well Permission is included.Bootskins at the moment are visible on my personal page,but not posted in BootSkins XP gallery.First time I uploaded them,I put permission file in skin folder before creating .bootskin file,so you could get it only after importing bootskin in BootSkin XP program,and opening related skin folder(Stardock/WinC/BootSkins/skins..).
I hope I don't get problems about second uploading.
