Sharing certain links on Skype triggers the program to show preview with image from the page. On a website I work on - there are big images on certain pages but Skype picks up the logo of the website instead. I was unable to find what meta tags would make Skype pick up the intended image and preview it.
I have a <link rel="image_src" href="http://www.example.com/path/to/img.png" /> that works for Facebook-sharing preview (img.png is used instead of the logo of the website) but doesn't work for Skype.
So how would you hint Skype which image should be used for preview?
I will need to find some source to support this, but I think that if you have defined some open graph meta data, it will pick the image specified in there. For example, I have these in one of my sites:
<meta property="og:title" content="Site Title" />
<meta property="og:type" content="website" />
<meta property="og:url" content="http://my.site.com" />
<meta property="og:image" content="http://my.site.com/images/thumb.png" />
<meta property="og:description" content="Site description" />
And the image displayed as the link preview on Skype is the thumb image specified in og:image (that is not available anywhere else on the page).
