I hope someone can help with this. I'm looking to post a deal on Ozbargain, but the banner on the website is quite wide and short, so it will look pretty bad as a thumbnail, which is obviously square on Ozbargain.
Is it possible to put a hidden picture in the head of the website (using the following <img src=URL style="display:none;"/>) and then have Ozbargain pick up that picture as the thumbnail without completely altering the way the website looks?
Sorry, it's been years since I did any HTML coding. It's a shame there's no preview on Ozbargain when it comes to thumbnails, otherwise I could just try it out, but I don't want to post a deal only for it to look terrible.
Thanks!
I don't think many care what the thumbnail looks like….
Edit: Without sounding too ignorant, shoutout to the front page Ozbargainers!
