I have purchased photos from istockphoto and have used some for my blog, including my home page. A friend recently told me I should give credit when I use these type of photos? I thought since I paid for them I had the "right" to use them in this manner (as opposed to selling the image or to make money in some way from them).
Can you let me know if I am being compliant?
The blog I need help with is footprintsonthecourse.wordpress.com.
