This isn't a big deal but is giving me cause to waste a disproportionate amount of time. You know when you want to share something on Facebook or you want to enter a link to another page or website? When the link details come up, there is a thumbnail picture from that website. Some websites have a number of pictures from which you can choose - the notation next to the thumbnail says 1 of 4 (if there are 4 thumbnails to choose from.
Okay - with me so far?
When I click on the Facebook share button on my 'Making Business Fun' blog I get as a thumbnail the only picture on my blog, which is a mugshot of me. (I presume the same happens for everyone else who wants to share my blog with their FB friends.)
Thinking that I would like a different thumbnail - even give sharers a choice of thumbnails - I entered some icon-type images to my blog hoping that they would be picked up by the Facebook 'share' app. But they are not being picked up.
Any idea how to get these other pictures to display at FB?
