Where did you hear this? I think you've got it all wrong.
There is free storage, limited to 2 gigabyte, for Photobucket, and with additional payment, storage space can be increased.
As to the Adobe confusion
, Adobe is migrating photos from photoshop.com to Revel and this does not have anything to do with Photobucket. Revel does not have any form of partnership or connections with Photobucket. You would have to download photos from Photobucket to your computer and then upload to Revel if you wanted to move them.
