My photos are on my pbase site. How can I submit Challenge candidates from there?

Thank you.

EDIT: A lot of the photos are of my toddler/baby nephews, and another group to which I belong (very much un-related to this forum) cautioned me against posting a link to images of youngsters, lest pedophiles do their evil deeds.

Owl, trying to get back to the PE Forum gang after neglecting you (giving you a break from my ramblings?) for so long
