Sure this is WP 2.3.3 – I’ve got the same in 2.5.1. Strange this is, I’ve got two separate WP 2.5.1 installed on the same server – one is perfect, the other one keeps giving me these “HTTP error” messages when uploading images.
I’ve got the same issue with 2.5.1. Multiple installs on the same server, and only one is broken (of course, it’s the one where the client wants to upload files every day…). It doesn’t matter what kind of file I’m trying to upload, they all fail the same way:
‘HTTP Error.’
‘An error occurred in the upload. Try again later’
It doesn’t even write any issues to the server error log (bit less than helpful…)
I am having the same problem. even tried uninstalling and reinstalling 2.5.1
Here another one. The same message: HTTP error. Is there already a fix?
Fix for the moment: For the time being:

It works but not ideal…
I had a similar problem with my blog. Was fine until I upgraded to 2.5.
If you have exhausted all other avenues, I would contact your host. My host (Hostgator) was blocking the upload of images for security. I had to tell them the location of all of my blogs so that they could remove the security feature. This worked perfectly.
When I was getting the problem I was just getting “http error”, but I know some people got “crunching” instead.
It seems that the server was logging this message: mod_security: Access denied with code 403. Pattern match “^Shockwave Flash” at HEADER(“USER-AGENT”) [id “***MY ID”][rev “1”] [msg “SpamBot UA”] [severity “CRITICAL”] [hostname “***MY-DOMAIN***”] [uri “/testing/blog/wp-admin/async-upload.php”]
Hope this helps you guys. I spent hours trying sugegsted fixes. I never would have guessed that it was a security issue with my host. After contacting them it was fixed within the hour.
At first they argued that it was 3rd party software, but I told them that I had a test blog and I also had blogs on 2 servers and it was the same on all of them. They referred me to their higher level support and they fixed it within an hour.
Let me know the outcome. dave@isnigh.com
I have had the same problem using Firefox. However, I can get the images to load using Safari.
If you are on a Windows machine, try using another browser. Also, I read on here somewhere one should delete cache memory. I did that and it created other problems so I restored all the cache files.
