As we have been working on digital citizenship a lot with our students and teachers, we are teaching them to make sure that they either provide original content or use images with a creative commons license.
In practice, this can slow down the publishing process to ensure that you are citing things correctly. More info about this here in this blog post
I found a great site that speeds up this process if you are going to use images for your blog.
For example, say I want this really cute image of this dog to put on my blog. First go to www.compfight.com and search “cute dog”.
