Quite a few times you may find that while sharing their own blog post link on social sites like Facebook, Digg, etc, the thumbnail image goes missing for no apparent reason! Most face this issue while sharing a link in Facebook, but some are finding this problem in other social bookmarking sites also.
This was the problem I was facing during my initial days of blogging. I searched for the solutions, but did not succeed and then. But later on I came across this solution. And now let me share that this solution does work.
These tips will not give your user, the option of selecting different images. So, you have to design your own image, which can be used here as Thumbnail for your affected site. It is better to use these tips rather than changing themes, plugins, and trying some other risky tricks.
First of all select an Image, which you want to show the users as thumbnails. You can take your website’s screenshot, or you can edit your website logo into a square one. 250×250 is better. (Square images looks good as thumbnails).
Upload your images to your site. If you are using WordPress, then upload it to your media library and note down the link (URL) of your newly uploaded image.
Now add a Meta tag of image source in between of < head > and < /head > of the html of your blog.
The Meta tag looks like this < link rel=”image_src” href=”http://yourblogURL.com/image.jpg” /> (Don’t use the space between < and link). Here change the href link to your uploaded image’s link.
This change will show your desired image while sharing in any social bookmarking sites. I hope these tips will solve your problem.
