I have images that I already uploaded before switching to WordPress 2.6 that I want to put into galleries and insert into posts. It looks like half the posts took the transition well and are shown as being attached, but a lot aren’t. How can I take an image that is already uploaded into my media library and simply put that in a gallery which I can then stick into a post?
It sounds like you are using a selfhosted WordPress install. Please head over to http://www.wordpress.ORG/support and ask your questions there. WordPress.COM is a different software implementation of WordPress and we cannot help you with self-hosted blogs. Thanks.
