Is there a way to add widgets or badges to a posterous blog?

Yes. I’ve done it on two blogger.com blogs. You need to take the code for the badges or widgets and add them to the coding on your blog where you want them to appear. What is the domain you want it on? Is it one of the wordpress.com blogs? Blogger.com? Your own wordpress script on your own domain? We need more details to assist further.

@Andreas It’s a posterous blog. Posterous doesn’t let you add javascript. Is there another way?

@Mtl_zack I suggest you visit the Fluther chat at http://www.fluther.com/chat/2/

I tried to find a .jpeg or similar, but no go. Chat would be your best bet. All the best. Please keep us informed.
