but if u try to
PP Admin panel > order images > click on 1 of 2 demo photos linkname > will get path error. (seems that images were not uploaded on correct location, but they are displayed :S )
by the way, why I had to modify the adm-misc and not using a standard one? is there an error on my installation?
