We have been discussing how important it is to attribute photos correctly, and that we cannot just google any photo and use it. That photo belongs to someone, we must have their permission to use it.
1. It is best to use our own photos or someone we know personally who we have asked and received the okay for.
2. Use Creative Commons to find a photo for our blog.
The easiest way to do this is add the Compfight plugin to your blog.
Go to Plugins on the left of your dashboard and click on All.
Compfight is at the top on the right and activate it.
Once it is activated there is a little camera to the right of Add Media and you can click on it and search for a photo you may use under creative commons and it includes the attribution. I think this is the best way for you at the moment.
