Some images are not posting/Cross posting

I have two blogs on my account. One is micro,blog hosted; the other is self-hosted. I’ve posted to both of these this morning, and some photos are not appearing on the blogs, (but some are). If I go into uploads page (the thumbnails for the offending images are blank, but clicking on the URL I can then display the image. They’re also not cross posting to threads and only some are posting to Tumblr.
