This is usually chickchair's domain. I built an application that allows her to easily upload images to the pic of the week. It automatically resizes the picture and pushes the old picture to the gallery here:
https://www.backyardchickens.com/images/chicken-gallery.php
The goal is to have a new pic added weekly on Sundays, but sometimes she isn't able to get them posted.
You can send pic of the week submissions to me and if I notice it hasn't been updated by Monday I'll be the "POW" backup boy and load one myself.
Remember, we want to keep the pics unique and special to the pic-of-the-week so we setup a few rules:
1) Submissions
must be "new" and can't be anywhere else on the net.
2) You must have the rights to the picture and allow BYC to use them how / when they want.
2) Once your picture is removed from the homepage of BYC and from the forum main page (and is on the gallery page) you can post it wherever you like.
Email them to nifty @backyardchickens.com
Any other questions please post them here!
BTW, first person to email me a picture can be the POW for this week!
