i have a very strange problem and never faced it before, its not problem with the plugin which i have installed but i don’t know why image tag doesn’t load few images although images are available on the url if you type same url in browser you will see image but i won’t load in the image tag kindly check the screenshot RSS link is displaying image properly on website but FACEBOOK and TWITTER don’t show images but if you copy same linke from TWITER or FACEBOOK in url than you can see the image.
Regards
