Picasa Web Albums has a functionality to transfer photos from your one account to another account. But, because of some problems, it recommends that not to use it. If you use it, may be your both accounts get stuck in a read-only state.
When you upload photos to Picasa Web Albums, the copies of photos will upload to the Google servers and the high resolution originals remain on your computer's hard disk. So, if you want to upload photos to your new account, then instead of downloading them and again uploading them to a new Picasa Web Albums account, you can simply upload the originals to the new account.
Picasa has a "Batch upload" feature which allows you to upload photos in a batch. If you do not know how to batch upload folders to Picasa, then you can follow the link provided here.
If you want to use the different Picasa Web Albums account, then you need to click "Sign out" link located at the Picasa's upper right corner. Picasa will prompt for a Web Albums logon name and password the next time you do an upload.

I have a large collection of photos and videos to upload on some of my storage account and I was looking for an application that can do it all automatically, and that it did especially well. I found a definitive answer to my needs thanks to this amazing program and that it is constantly improving whith new fantastic features.
PicBackMan was really easy to setup and has been running for 3 days now backing up all my locally saved photos to Flickr. My photos are really valuable to me so it's great to be able to have them easily backed up to a secure location.
PicBackMan was an answer to many a prayer. How can I get this MASSIVE collection of photos onto a service that cripples uploading? PicBackMan. I uploaded approximately 85,000 photos in less than a month. It would have taken me close to a year to get all of those photos where they needed to go. Nothing short of brilliant.
LOVE this program! Works better than ANY other program out there that I have found to upload thousands of pictures WITH SUB-FOLDERS to SmugMug! Thank you so much for what you do! :) #happycustomer
