I've recently moved my blog from wordpress.com to stand-alone hosting using the 3.5.1 platform. Uploading images used to be extremely fast and efficient but now it's nigh on unusable. If I attempt to upload more than one image at a time the first will freeze after a certain percentage or go into crunching mode where it will just hang. As a result the next image never begins to upload. Uploaded on their own, single images seem fine, so it's only when multiple images are uploaded at the same time.
I've searched for help but all I find are topics like this:

The site in question is:
I have the exact same problem on a relatively new site that I've created for my business which is also using 3.5.1 but has always been hosted as a stand-alone.
I'm using the latest Firefox and Chrome browsers, the hosting is fast and has never caused any upload problems previously and doesn't on my third site which is not wordpress based.
Any relief from the pain would be great appreciated. :-)
