My images on the sales page of codecanyon does take effect with my new image. As I check the path of the images and I soon got to know that the image path is not coming from my own server it’s coming from cloudfront.net, Is this a new feature of envato for caching.
Yep! We started rolling this out a few weeka ago to our users. Check out Rollout of HTTPS proxy for author hosted imagery for more details.
Thank you so much Jacob for the reply and for the info.
