Image Uploader and HTTP Error

I do not see this in the sticky thread. When I try to upload an image, the image appears to upload to 100%, but then a red “HTTP error.” appears right under the “Upload New Media” header. The image goes into the Media Library, but it says it is (0x0) in size, and i can’t adjust anything. However, I can put it in a post, but it is huge.

Funny thing, it has worked before. I’m tired of trying to reinstall WP and reconfiguring the database set up again, the problem continues to persist. This is happening on two separate set up/blogs that I am managing.

Please help:

I’m using WP 3.0.1 on Mac OSX 10.6.4 with Safari 5.0.1 or FireFox 3.6.10 (doesn’t matter, happens in both)
