I've never really done much with the built-in WordPress media library. I tend to create a full size and thumbnail version of my photos with Paint.NET and upload both sizes to a folder and link to the full size from the thumbnail version.
I'm setting up a blog for some people who don't want to have to use an image editor like Paint.NET to generate thumbnails.
After clicking "Add an Image" when editing a post or writing a new post, I select the image I want to upload. It uploads, says it's crunching and all that good stuff. Eventually it's added to the gallery for that post.
However, when I go to actually insert the image into the post, the only size option I have is "full size", which I obviously don't want. It seems like thumbnail and the other sizes aren't being created.
Permissions on the wp-content/uploads folder is 777. The original size makes it into the uploads folder just fine, just never any other sizes.
Can anyone advise on what I'm doing wrong or if I'm missing something?
