Yo i've made a texture set, i uploaded legs and everything was ok, but when i'm trying to upload head there's that error "Could not copy to /var/www/www.toribash.com/htdocs/cp/customupload/PanSowa/head.tif"

2nd problem
Nobody answered to my questions on pov-ray head thread so if somebody know what i'm doing bad please write it there http://forum.toribash.com/showthread.php?t=52554&page=12

Hmm 2nd problem will be fixed soon probably, as someone who knows about that answers.
For the first one: Have you tried uploading a different picture, do you always get that error message?

1st problem solved - i glued all layers into 1
2nd still unsolved
