I know this isn't really affiliate related... but it is for an affiliate site. My site is based on a medical disorder. I'm noticing that my competition has plenty of pictures of the conditions (within the condition) and I'm having trouble finding any on stock sites. It seems like a lot of people are using the same photos, as well. I'm not sure what the policy is on this, in order to acquire these pictures, or if anyone knows where I may be able to get pictures related to medical conditions? I appreciate any help. I feel like pictures help sales and also help the topic/site look more legitimate.
