I just installed Atahualpa on my blog. I've only done two test posts, and the first time I try to upload an image (either from my iPhone using the WP app or "From My Computer"), the image appears on the homepage as a gray box with three black lines moving through it. I can't replicate the problem with the default theme, so I imagine I have something set wrong with Atahualpa. If someone can help me out, I'd be much obliged.
(my blog is at pocketsymphony.com, btw)
