How to add additional image options on Digg and Facebook
Here is a really quick Digg.com and Facebook.com tip:
When a link is shared on digg or facebook, the user gets to cycle through a couple photos on the page to add as a thumbnail.
If you want to add additional images as options all you need to do is add html image tags to your website code and hide them with some css. I prefer to add them directly after the <body> to force them as the default image on digg.
Here is the code :
<img src="replace with image link" style="display:none;"/>
Note: Even though your image does not appear on the web page, it is still being loaded. Be careful using very large images. It can slow your pages load time.
