Image Resizing Issues in 2.0.1

Will someone please help me with this issue? I’m using WP 2.0.1, and I’m trying to upload photos to appear as their original size in posts and pages. After I upload, I select “Using Original” then “Send to Editor,” but the images are showing as thumbnails instead of the original sizes.

I’ve checked the forum for an answer, but similar questions have gone unanswered. If you have even a suggestion, please post it. Thanks.
