Sciblogs has channels (e.g env, which is where I live, except for posts like this, which go onto chatter) and they are looking for new pix to adorn the banners, which will rotate on a weekly basis. The instructions are: “It’s not too hard: the image needs to be at least 465 pixels wide. Readers should send their photos to email@example.com. They should send only photos that they have the rights to (eg, photos they have taken themselves), and they should include a line of text to the effect that we have permission to use their photo on ScienceBlogs. They should also add how they’d like to be credited, and whether they would like a link to appear along with the credit. (If there are identifiable people in the photo, we will need to have their permission to post the photo.) People can also send us links to Flickr pages, or tag a photo on Flickr with “Sb-homepage,” and we will find it. They should make sure that the photos are licensed under Creative Commons with an “attribution only” or a “share alike” license.”
There you go.
