Which version of PWG are you using ?
If you're using PWG 1.3.4, just modify /template/default/picture.vtp
If you're using PWG 1.4, just modify /template/default/picture.tpl
Does anyone know how to move the picture path and title to the bottom of the page? At the moment it appears above every photo, which means each user needs to scroll down in order to get a full view of the image.
