The way you add pictures right now is only by cell phone through picture message. Early next week we will add photos upload from the website.
You read it here first folks. Next week, Yappd will allow users to send images along with their posts. I don’t want to bag on Yappd anymore than I already have, (see my review Yappd Reviewed – Non Twitter Killer ) But this feature should of been released with the service on day 1. However, I’d say thanks to Yappd for responding to my email.
