I've just built a lovely website - gretchenmiller.com.au ... lots of effort and time!
But when I added it to my linkedin profile it came up as a random grab from the page, in close up (specifically the dotted lines in the middle - not one of my carefully selected images.
I've searched the 'help' pages here to try to understand why, but can't find anything. I don't have anything in my headers/footers cos I have no idea what function those bits serve... but has that got something to do with it?
I think LinkedIn is using that image because it's the first image on the page that meets its criteria. Try adding another standard image element above it on the page. Hopefully LinkedIn doesn't cache site data like Facebook so it will scrape the page again and see the new image.
I did find this article when I was Googling which might also be helpful:
Thank you... I do have the header image, I guess that doesn't count. Shame, because I don't really have a place for another image!
Hmm... You could try adding this to Settings > SEO > Header Code:
<meta property="og:image" content="http://www.gretchenmiller.com.au/uploads/1/1/2/0/112093385/background-images/2122517149.jpg">
I'm not sure if LinkedIn would use it since the other image is listed first in the code, but it's worth a shot.
