Image not showing when sharing to FB

Hi All,

I’m using the command “FB.ShareLink” to share a FB post.
When i try to share this picture:
http://sheep-service.info/TheOfficeQuest/Pics/pic.png

It share the post with empty picture.

But, when i try to share the same picture from different location:


It shares the post with this picture.

So my questions is: Why does the picture shows only from the second location? do i need to configure something on my facebook app page?

From my experience as a web developer, Facebook uses Open Graph Meta tags to produce their preview cards. I’m guessing sheep-service.info is your personal site. I’ve never tried just sharing images (I’ve only worked with shared links) but I assume Imgur has some system built in to pass header info along with the image, where your site may not.

More of a guess than anything, though.

Thanks for response.
I guess you guessed right, i’m looking for solution for that, maybe put a html script instead of PNG?
