Let me keep this simple for all the non-lawyerly types out there.
Link to any of these pages on the site without asking for permission
Add this site to a blogroll or a directory (as long it's not porn-related)
Hotlink to any of these pictures on the site i.e., embedding them on your site while pulling the image from my site.
Copy or use these pictures in any manner, commercial or personal, without asking my permission first. No, Times of India writers, you are not magically exempt from this.
Post this on any website or social media group without permission. Yes, I know it's covered above, but some people still don't get it.
Summary: Linking is fine. Copying and posting is not. Simple, right?
