What are the best practices in sourcing copyrighted material for a website using Adsense? Do images need to be clickable and linked back to the source, or will simply providing a text link back to the sources website suffice?
I know of a website in the plastic surgery niche that has been banned recently from Adsense. I am curious to know the reasoning behind it and if it's due to them not properly sourcing the images on their site.
The only thing to do is contact the copyright owner and ask for permission, and under what terms you may use the images. There's no "best practice" that will cover you for all situations, it's all a matter of getting permission on a case-by-case basis.

Those are both myths.
You may want to research what Fair Use is, which should give you guidance on what the permissable limits are. Here is a US Government web page about Fair Use that may be a good starting point for your research:

And be aware that even with claiming 'fair use' a photographer can make it so un-worth your while, expensive, and troublesome--especially if the copyright has been registered. Best to talk to an attorney before interpreting 'fair use' in your application. Best bets are to take your own shots or hire a photographer. Personally, I pursue misuse of my work vigorously, and it has worked to my financial benefit. It is just another kind of scraping. Everybody claims 'fair use.' It's good to know I can also report them to Adsense.
