I, like many of you, have found when uploading multiple photos, ie 10 or more, the speed is slow. Much slower than the old version. When I contacted Photobucket to let them know of the issue, they sent me the following instructions:

I'm sorry to hear you're having issues! Let's start troubleshooting with the following:

First, please clear out your browser's cache and cookies. You can learn how to do that with this article:

Please make sure your browser is supported and ***up to date***:

Then, let's make sure you have the most current versions of Flash:

Also, check to see if Javascript is enabled (Javascript is different from Java):

I had already done all of those things and still have a slow speed. The tech support person wanted me to take a screen shot of the issue. Well now, just what will they see but spinning circles while the photos are uploading and it is only a point in time when doing a screen shot. Photobucket claims they haven't changed anything with regards to uploading.
I wish they would get the developers involved to correct the issue. We use to be able to do a bulk upload and it went fast.
JMO.
